▼ Dwindling fossil fuels coupled with changes in global climate intensified the drive to make use of renewable
energy resources that have negligible impact on the environment. In this attempt, the industrial community produced various devices and systems to make use of
solar energy for heating and cooling of building space as well as generate electric power. The most common components employed for collection of
solar energy are the flat plate and evacuated tube collectors that produce hot water that can be employed for heating the building space.
In order to cool the building, the absorption chiller is commonly employed that requires hot water at high temperatures for its operation. This thesis deals with economic analysis of
solar collector and absorption cooling system to meet the building loads of a commercial building located in Chattanooga, Tennessee. Computer simulations are employed to predict the hourly building loads and performance of the flat plate and evacuated tube
solar collectors using the hourly weather data. The key variables affecting the economic evaluation of such system are identified and the influence of these parameters is presented. The results of this investigation show that the flat plate
solar collectors yield lower payback period compared to the evacuated tube collectors and economic incentives offered by the local and federal agencies play a major role in lowering the payback period.

▼ Bulk Hetero-Junction - (BHJ) - Organic photovoltaic (OPV) cells based on the conjugated polymer poly (3-hexylthiophene-2, 5- diyl) (region-P3HT) also referred to as P3HT and a fullerene derivative [6, 6] Phenyl-C61-butyric acid methyl ester (C60-PCBM) also referred to as PCBM. The optimization, realization and characterization of these cells were done on both glass and aluminium substrates. The aluminium provided a flexible substrate for the cells whilst the glass provided a rigid substrate and acted as a control. The thin films for the solar cells were deposited by means of the spin coating method.
The integrity of the starting materials were evaluated using Fourier Transform infra-red (FTIR) and x-ray diffraction (XRD) spectroscopy whilst the particle size and distribution, were examined using XRD spectroscopy and transmission electron microscopy (TEM). The electrical characterization was done using a 4-point probe and gas sensing methods. The morphology and roughness of the local composition of TiO2 thin films before and after annealing were evaluation by means of atomic force microscopy (AFM).
The study eventually evaluated the effects of blend ratio and annealing temperature on photo-absorption of the blends. Blend ratios examined in the study fell within the range of 1:0.8 to 1:1 by weight of P3HT to PCBM. The range was divided into 11 intervals with a step increment of 0.02 for PCBM while P3HT was kept constant. The optimum blend ratio was determined and found to be 1:0.96 at 130 °C annealing temperature and duration of 30 minutes. The annealing temperature dependence of each blend ratio with respect to photon-absorbance was found not to be symmetric but random. Each blend ratio was found to have own optimum annealing temperature.
The efficiency of the cells was enhanced by the use of TiO2 thin film as a back reflector and optical spacer on aluminium substrate. The study compared the performance of cells on glass substrate to those on aluminium substrate. The cells built on aluminium substrate showed a power conversion efficiency of 2.8 % whilst those on glass substrate showed 1.9 % efficiency.
The main objective of the study was to determine the optimum blend ratio, the optimum annealing temperature, and to eventually build solar cells from the optimized parameters.

▼ Energy is very important for the development of any country in this world and Malawi is not exceptional. Malawi depends mainly on the Hydro Electric Power, fossil fuels and biomass on its energy sources for social economic and industrial activities. Due to increase in demand, Electricity Supply Corporation of Malawi (ESCOM) has more pressure to supply the power to increased number of industry and domestic use which lead to more frequent blackouts throughout the country. In this regard there is need for an alternative source of energy, and solar energy is the most common and easy to get.
The main objective of this study is to assess the potential for solar energy generation over Malawi, results of which would lead to harnessing solar energy in the country. The monthly mean sunshine hours and solar radiation values for the period of 30 years from 13 sites were analyzed in this study.
Monthly and seasonal variations of sunshine hours and solar radiation were determined. Long time trend were also determined. The analysis has shown that there is higher solar energy potential in the Northern, Lakeshore, Central areas and the Southern tip of southern region. The analysis has also shown that most of the areas in the Southern highlands of Malawi have low solar energy potential. The study further show that there is seasonal variation of solar radiation within the season of the year; March, April, May, August, September, October and November being the months of highest solar radiation utilization while December, January, June and July has lower solar radiation utilization potentials.
This research recommends the people in the area of study to put into consideration in this form of energy. They should invest and use solar energy as a reliable source of energy more especially in the rural areas where only 1% of the population has access to Electricity. More research needs to be done in order to get accurate estimate of available solar energy in Malawi more especially at regional and districts levels

▼ In the previous decades, people raised the awareness of the shortage of fossil fuel in the coming forty to fifty years. Besides, the reduction of CO2 emission is paid attention. Among the renewable energies, solar energy has the highest potential to be the main energy source in the future to solve the mentioned problems.
In the last few ten years, the technologies of solar energy were improved and used more widely as an energy source. The solar energy is used in several different ways. It can be used as heat energy for water heating or space heating. The solar thermal energy can be used with active or passive design. There are direct and indirect designs regardless the active or passive energy system. The efficient and the cost effectiveness are according to the designs of the systems. The places and the climate of the buildings where they locate are the main considerations of the system design. With understanding more about the differences of the existing solar energy systems, they can be applied in more efficient, cost effective and environmental friendly.
Regardless the dimension of the system, solar energy is the trend of the energy source for heating and electric power. It is not only used in building, it can also used for producing hydrogen fuel cells which will be using in transportation.

▼ The current energy scenario in the developing nations with abundant sun resource (e.g. southern Mediterranean countries of Europe, Middle-East & North Africa) relies mainly on fossil fuels to supply the increasing energy demand. Although this long adopted pattern ensures electricity availability on demand at all times through the least cost proven technology, it is highly unsustainable due to its drastic impacts on depletion of resources, environmental emissions and electricity prices. Solar thermal Hybrid power plants among all other renewable energy technologies have the potential of replacing the central utility model of conventional power plants, the understood integration of solar thermal technologies into existing conventional power plants shows the opportunity of combining low cost reliable power and Carbon emission reduction. A literature review on the current concentrating solar power (CSP) technologies and their suitability for integration into conventional power cycles was concluded, the best option was found be in the so called Integrated solar combined cycle systems (ISCCS); the plant is built and operated like a normal combined cycle, with a solar circuit consisting of central tower receiver and heliostat field adding heat to the bottoming Rankine cycle. A complete model of the cycle was developed in TRNSYS simulation software and Matlab environment, yearly satellite solar insolation data was used to study the effect of integrating solar power to the cycle throw-out the year. A multi objective thermo economic optimization analysis was conducted in order to identify a set of optimum design options. The optimization has shown that the efficiency of the combined cycle can be increased resulting in a Levelized electricity cost in the range of 10 -14 USDcts /Kwhe. The limit of annual solar share realized was found to be around 7 % The results of the study indicate that ISCCS offers advantages of higher efficiency, low cost reliable power and on the same time sends a green message by reducing the environmental impacts in our existing power plant systems.

▼ Held every two years in Washington DC and run by the US Department of
Energy the
Solar Decathlon is a competition that challenges architecture
and engineering students from all over the world to come up with new and
innovative ways to design and construct low
energy homes. For the first
time in the competition’s history a team from New Zealand was selected
to compete in the 2011 competition. This thesis documents the design
process of the First Light house from concept to construction focusing on
the relationship between
energy and architecture in a New Zealand home
designed for the
Solar Decathlon.
The challenge for the young architects and engineers competing in the
competition is to develop ways of reducing
energy consumption and to
raise awareness of the
energy saving benefits of highly efficient home
design to the public. Despite this being the underlying philosophy, this
thesis suggests that the competition is structured in a way that rewards
technology over passive design innovation in architecture. A typical
Solar
Decathlon house is epitomized by a large
solar array generating the power
needing to run an oversized mechanical system. The New Zealand entry
challenges this trend with the design of a home that is focused on ways to
improve passive strategies for reducing
energy use first before relying on
technology. The question is whether a home designed with this philosophy
in mind can still meet the strict requirements set out in the ten contests
embedded in the
Solar Decathlon?
Designing a home to meet these requirements was also, in many ways,
contradictory to the house’s philosophy. The conceptual driver of the First
Light house was the iconic ‘kiwi bach.’ Commonly defined as “something
you built yourself, on land you don’t own, out of materials you borrowed
or stole,” the bach gives a unique model of comfort and how people
might live in a space. Its values are associated with a relationship with the
outdoors, a focus on the social aspects of the home and a simple use of
technology. As the project developed it was also apparent ‘the bach’, if it
were used all year round, could become a symbol for the current state of
many New Zealand homes; cold, damp, unhealthy and wasteful of
energy.
Finding ways to improve this while maintaining the essence of the bach
became one of the major motivations throughout the design process. The
challenge with this was that the goals associated with designing a ‘kiwi
bach’ for a New Zealand climate were, in many ways, conflicting with the
requirements of the
Solar Decathlon competition.
Using comprehensive thermal modelling the First Light house was
designed as a net zero
energy home that could meet the requirements of
two quite unique briefs for two distinctly different climates. Throughout
this thesis the often contradictory relationship between the First Light
house as a
Solar Decathlon entry and the First Light house as an
energy
efficient ‘kiwi bach’ is explained. Broken into three parts the thesis looks
at the passive design of the home and the optimization of the…

energy will increase. The Federal Government has begun to address the challenge of
energy production and
energy security in recent years. In order to increase both the
energy production and
energy security for the Air Force, there is a trend to increase the amount of renewable
energy produced on military installations. The goal of this research was to compare the estimated and actual performance of these large-scale on-site renewable
energy projects at Air Force installations. The variables considered for this research were the execution methods and the renewable
energy sources. The performance of each project was evaluated against factors identified in previous sustainable construction studies. The study found that actual performance of third party owned and operated projects differed from the expected performance by less than the Air Force owned and operated projects, and that performance of renewable
energy projects differed from the expected performance by less than high performance buildings from previous studies. The study also found factors that contributed to the gap between the expected and actual performance including optimistic modeling, unusual weather, operational issues and higher than expected maintenance of the projects. The results of this research were an initial step in understanding the actual performance of large-scale renewable
energy projects.

▼ A number of research and development groups and several renewable project operators have examined combining wind power production with on-site
solar power
production. Past research has been devoted to small, off-grid applications only. In the absence of actually building a utility-scale project, short time scale (5 minutes) estimates of combined power production are difficult to simulate due to the lack of hub-height wind data combined with on-site
solar insolation data available in similar time scales. This presentation will present hub-height, high-fidelity, wind data from the Texas Tech University’s 200-meter meteorological tower combined with a co-located
solar
pyranometer to estimate short-term (5-minute) power production data. Recent reduced costs associated with
solar-PV may make this option more attractive in the future. This
analysis addresses fixed-plate, single- and dual-axis PV arrays.
This presentation also includes an economic analysis of the wind-only,
solar-only, and combined wind-
solar plants. Over the past few years, renewable
energy has entered the electrical grid at an exponential rate. To reduce the uncertainties for the grid operator, wind power plants “firm” their production under power purchase agreements (PPA’s) paying penalties when the “firm” production is not met. This puts more risk on the wind power provider in order to secure a higher sale price. Since wind power is best at night and
solar power is only during the day, by combining their synergies, uncertainty is reduced and higher PPA’s are possible. This analysis will present economic estimates
of the ability of plant operators to secure higher purchase prices for power by raising the
“firm” production level and reducing the uncertainties.

▼ Despite a lack of incentives,
solar photovoltaic
energy is gaining traction in British Columbia. Privately owned home and commercial systems are on the rise and an increasing number of community led initiatives are experimenting with various models for
solar photovoltaic
energy delivery. Using the business model as an analytical tool, the present study explores the range of models by which individuals and organizations have begun to harness and distribute
solar PV in the province of BC, and the barriers, bridges, and critical success factors for each. A number of contextual conditions are identified that have contributed to two general categories of models that have arisen: commercially led approaches that focus on customer owned systems (i.e. individual home or building owners) and community led approaches that focus on community owned and/or financed systems. The study provides insight for others wanting to implement
solar energy for themselves or their communities.

▼ A
solar updraft tower power plant – sometimes also called '
solar chimney' or just ‘
solar
tower’ – is a
solar thermal power plant utilizing a combination of
solar air collector and
central updraft tube to generate a
solar induced convective flow which drives pressure
staged turbines to generate electricity.
Several technologies exist that can convert
solar energy into electrical
energy. The
solar
chimney is part of the
solar thermal groups of
solar conversion technologies. Of these
technologies the
solar dish has the highest
energy efficiency (the current record is a
conversion efficiency of 30% of
solar energy).
Solar trough plants have been built with
efficiencies of about 20%. The
solar chimney has an efficiency of less than 2%. However,
due to its greater scale and simplicity, the
solar chimney may have an economic
efficiency approaching or exceeding that of the other methods.
To improve efficiency of the plant thermal storage system is used. Thermal storage
system improves the power output by re-shaping the profile of the power output. The
most commonly suggested method for creating
energy storage is to place extra thermal
mass under the collector in the form of black containers of water.
In this paper both the
solar chimney power plants: the plant with and without thermal
storage system are simulated for the case of Afar region using Fluent and the effect of
turbine position is also analyzed. The cost of the power output per kilowatt-hour is
reduced while using the thermal storage system. It also regulates the power output. The
power output increases as the turbine is positioned at higher position but the cost of the
chimney so the plants cost increases very much.
Solar chimneys are very suitable for use in remote communities where there is high
solar
energy capacity; such as Afar and Somalia, as a power source for both residential and
industrial use, based on reliability, cost, and operational factors. They can provide a
suitable
energy source in many remote areas of Ethiopia, including areas that are not
currently supplied by conventional means.

▼ The Group for
Solar Energy Thermodynamics (GSET) is in the process of commissioning the
Solar Energy Research Amplified Flux Facility (SERAFF), which is South Africa’s first
solar furnace facility. SERAFF is situated at the University of KwaZulu-Natal’s Howard College campus and assumes an on-axis optical configuration, comprising a 9 m2 non-focusing heliostat reflector, a 3 m diameter paraboloidal dish concentrator and a test article platform. The facility was designed to aid research in the fields of high temperature materials testing, concentrating
solar energy and
solar thermochemistry. The concentrated radiative
energy output of a
solar furnace establishes the
energy input to prototype receivers, reactors or materials that aim to be tested using the facility.
The challenge is compounded by the temporal and spatial variation of SERAFF’s radiative
energy output, influenced by weather-related and geometric factors. In this study, an indirect spatial flux mapping system is developed to characterise SERAFF’s spatial radiative
energy output. SERAFF’s theoretical spatial radiative
energy output is estimated through Monte Carlo ray-tracing techniques to provide benchmark performance parameters including total thermal power output, peak concentration ratio and focal spot size. The indirect system uses optical measurement techniques, in which spatial
solar flux is measured via diffuse reflection off a Lambertian target using a digital CMOS camera through a neutral density filter and lens. Pixel intensities are calibrated against reference measurements acquired from a circular-foil Gardon gauge heat flux transducer. The calibrated CMOS camera can be used to measure values of radiative flux, incident at the focal plane from 0 kW/m2 - 468.19 kW/m2.
Measurements were restricted to a brief testing period and are not representative of SERAFF’s peak operating conditions. Spatial flux measurements indicated a thermal power output of 3.83 kW, with a corresponding peak
solar flux of 227.8 kW/m2 within a focal diameter of 250 mm. The study demonstrated successful integration of an indirect spatial flux mapping system into the SERAFF
solar furnace.

▼ Solar energy is still not being used effectively in countries in the developing world, though it's a partial solution to the problem of shortage and expensive energy. Normally harvested through flat plate collectors, converting solar radiation into heat is the most direct application that can be effected in water heating systems. Many researchers have attempted to develop means of improving the efficiency of the flat plate solar energy collector; however there appears to be no evidence of any work regarding the effect of geometric configuration on the performance of flat plate solar collector.
This study presents results obtained when comparing the performance of a solar water heating system equipped with three manufactured flat plate solar collector panels of numerically identical surface area but of different geometric configuration as they were individually attached to a typical geyser. Data was obtained inside a laboratory. The amount of heat acquired from flat plate collectors of solar energy depends primarily on their surface area that is exposed to the solar irradiance, however, the geometry of the collectors was thought that it might affect to some extent the amount of heat harvested. The circulation of the water from the panel to the geyser was due to the self-induced thermo-syphon effect. The results obtained during the test period (7 hours per day for two consecutive days) indicated that the system’s thermal efficiency was best when the square geometrical configuration collector was used. A dimensional analysis using the Π Buckingham method that was performed on the parameters affecting a flat plate solar collector yielded three dimensionless numbers that lead to a power law relationship which might be useful in enhancing solar water heating systems’ design.

▼ Abstract: This work presents the synthesis of carboxylated molecules and their use as compatibilizer agents in hybrid inorganic/organic systems. Characterization and application of the interfaces of those hybrid systems comprising titanium dioxide with poly(3-hexylthiophene) (TiO2/P3HT) and monocrystalline silicon with poly(3-hexylthiophene) (Si/P3HT) will also be described. In the former system, TiO2/P3HT, the TiO2 surface was modified with three molecules: 2-thiophenecarboxylic acid (TCA), 2-thiopheneacetic acid (TAA) and 2,4- thiophenedicarboxylic acid (TDA). Transient Absorption Spectroscopy (TAS) photophysical studies and contact angle measurements demonstrated that TAA presents the best compatibility in the interface.
Solar cells modified with TAA, set up in inverted configuration, showed 0.03% of overall
energy conversion efficiency, which is three times larger than the one obtained from a standard device. Replacing TAA by N719 dye on TiO2 surface increased the efficiency, achieving values higher than 1%. Inserting TiO2 rod-shaped nanoparticles (TiO2 NB/TAA) on P3HT layer of the latter system resulted in 1.35% overall efficiency. Photoelectrochemical experiments demonstrated that this modification using TiO2 NB/TAA increases exciton separation rate and conductivity properties slightly enhanced compared to spherical nanoparticles (TiO2 NE/TAA). Small-Angle X-ray Scattering (SAXS) showed that TiO2 NB/TAA and TiO2 NE nanoparticles are homogeneously distributed in the P3HT matrix. In the Si/P3HT hybrid system, the inorganic/organic interface was modified through chemical adsorption of TAA molecules on the native oxide (Si/SiOx/TAA) and a reaction of the surface Si-Cl groups with Grignard reagent 2-thiophene-magnesium bromide (Si/Tiofeno). Both reactions were characterized using Infrared Spectroscopy (FTIR) and X-ray Photoelectron Spectroscopy (XPS). The contribution of P3HT to the p-n junction formation in the photovoltaic device was evaluated from a comparison with a Schottky junction (Al/Si/Au). The VOC values obtained with P3HT were similar among the experiments (around 0.4 V) and higher than without the polymer (around 0.2 V). This observation highlights the dominance of Si/P3HT for photovoltaic properties. The Si/SiOx/TAA device exhibited a high series resistance, with
energy conversion efficiency lower than 0.5%. However, using Al/Si/Tiofeno/P3HT/Au configuration, the
solar cells reached 5.76% efficiency. The higher values might be related to a better adhesion and compatibility between Si and P3HT, which was observed from SEM images

▼ Apresenta-se o aproveitamento energético da utilização de coletores solares para aquecimento de água para banho em duas habitações unifamiliares na cidade de Santana de Parnaíba, Brasil e na cidade do Porto, Portugal. Para a análise em questão deve-se verificar a potência de irradiação solar nas duas cidades, considerando os hábitos da população, cultura, condições geográficas e meteorológicas.
Foram dimensionados e projetados 2 sistemas equivalentes para residências com 4 moradores e em seguida calculado seu custo através do Guia de Parametrização de São Paulo. Pode-se verificar a viabilidade das instalações de um sistema de aquecimento solar térmico nas duas edificações foi satisfatória e o retorno do investimento se dará por volta de 30 meses. O outro sistema tornou-se inviável para esse porte de edificação.
It presents the energy use of the use of solar collectors for heating water for bath in two single-family homes in the city of Santana de Parnaíba, Brazil and in the city of Porto, Portugal. For the analysis in question must check on the power of solar radiation in the two cities, considering the habits of the population, culture, geographical conditions and weather.
Designed 2 equivalent systems for homes with 4 residents and then calculated its cost through Guia de Parametrização de São Paulo. You can see that the viability of the facilities, a heating system of solar thermal panels in the two buildings was satisfactory, and the return on investment was around 30 months. The other one has became unviable for this type of building.

▼ A promising and novel solar concentrator design has been thoroughly investigated and optimised. A prototype concentrator based on this novel geometry was validated using ray tracing techniques. This ray tracing demonstrated the comparative performance of this novel concentrator in regards to equivalent parabolic dishes. The effect of mirror surface normal errors on performance was established using Monte-Carlo based ray tracing code, which agreed well with the optical performance of this prototype which was determined experimentally. A need for low-cost solar cookers to replace bio-mass worldwide was identified, and the concentrator design was then developed as a low-cost solar oven. Despite existing in some number, no current design is able to achieve high performance at low-cost. An industrial partner, Dytecna, was initially involved in the process of this development of the system as a solar cooker. In support of a field trial for the solar cooker developed with Dytecna, a detailed thermal model of the oven was developed. A low-cost lightmeter was constructed and calibrated in order to measure the direct normal irradiance during the field trial in Italy. Laboratory work provided baseline results for the heating of various thermal masses in the oven. The Italian field trials provided a wealth of feedback into the design of the system and many valuable results. The solar cooker was able to bring 0.75L of water to the boil in 33 minutes with an average heat throughput of 203W. Important benchmark results and practical experience of several competing receiver materials was obtained; further lab testing provided more accurate measurements of the receivers' performances. The experiences of the Italian field trial were fed back into the design of a subsequent prototype, intended for a much larger field trial in Tanzania. Improvements in the hotplate, receiver material, and the oven were all incorporated into the design. Additionally, the structure of the solar cooker was redesigned to incorporate a low-cost wooden construction. Supporting work was conducted for the month long trial in which 8 solar cookers would be distributed to families in Tanzania. The field trial in Tanzania provided a wealth of user feedback into the design. At the same time the new solar cooker exceeded previously established performances in Italy. The new design was able to provide an average of 246W of heat to 1kg of water, which was brought to boiling point in 25 minutes. This represents a heating efficiency of 66% compared to the incident solar flux on the hotplate. In response to findings during the Tanzanian trials, further laboratory work was conducted into establishing the reflectivities of low-cost candidate mirror materials. Throughout all phases of the project the design of the solar cooker was refined and improved with the goal of a solar cooker design that could reach price-point, performance, and usability standards which would ensure market success.

▼ Many local governments across the United States are experiencing a new political willingness and drive to create sustainable
energy goals. While this marks a very positive shift towards a more sustainable future, those agencies are finding that there still exist many barriers along the path towards meeting their
energy goals. This study investigates
solar collaborative procurement as a means for local governments to confront the barriers they face in trying to achieve
solar photovoltaic (PV) adoption.
Market Identification research conducted in this study was designed to identify future participants of the Sustainable
Energy & Economic Development Fund (SEED Fund), a program run by this study’s client organization, Strategic
Energy Innovations. The SEED Fund is a
solar collaborative procurement program for public agencies that utilizes a revolving fund to offset the upfront costs associated with
solar PV adoption.
Employing “lessons learned” from former
solar collaborative procurement projects, this study designed a methodology with which market identification research was performed. The goal was to identify geographical regions where SEED Fund might find a receptive market for their services. Four iterative approaches were applied to develop this market research:
1. A literature review on
solar markets in the US;
2. A filtering methodology was created to identify regions with the highest likelihood of successful participation in a collaborative procurement effort;
3. Interviews were conducted on public agencies identified by the filtering process;
4. Surveys were sent to additional agencies within counties that the filtering process identified.
This methodology successfully identified regions that have strong potential for engagement in a
solar collaborative procurement effort, including Los Angeles and San Diego Counties in California, and Larimer County in Colorado. While these three counties have shown strong interest in the collaborative approach to
solar adoption, Los Angeles’ interest was particularly keen. LA has indicated that they may want to move forward with participation in the SEED Fund program much sooner than this study had anticipated. Due to this enthusiasm, work is currently underway to establish Round 2 of the SEED Fund in the Los Angeles area.
This practicum study appears to have been effective at 1) Creating an effective market identification method and 2) using this method to identify market actors for the SEED Fund to pursue in the near future. If acted on, this study could lead to a significant expansion of public
solar PV, especially in Southern California. Additionally, the methodology developed in this study has established a durable mechanism by which new regions can be identified for collaborative procurement in the future.

▼ Air-conditioning systems driven by solar energy have can save primary energy and reduce peak power consumption, which is particularly important for utility providers in the summer months. Additionally solar cooling is a promising application of solar thermal technology since the cooling load is well correlated to the overall solar availability. Liquid desiccant air-conditioning, which uses a salt solution to dehumidify air, can be used in a thermally driven air-conditioning system and offers many benefits for solar applications including the ability to store solar energy in the form of concentrated liquid desiccant.
The current work focuses on the Queen’s University Solar Liquid Desiccant Cooling Demonstration Project. In previous work, a pre-commercial Liquid Desiccant Air Conditioner (LDAC) was installed and experimentally characterized using a gas-fired boiler to provide heat. As part of the current study a 95m2 solar array was added as a heat source. The Solar LDAC was tested for 20 days in the summer of 2012 to evaluate performance.
The solar LDAC was found to provide between 9.2kW and 17.2kW of cooling power with an overall thermal Coefficient of Performance (COP) of 0.40 and electrical COP of 2.43. The collector efficiency was 53%, and 40% of the required thermal energy was provided by the solar array.
A model was developed in TRNSYS to predict the performance of the solar LDAC and simulation results were compared to the experimental results with reasonable accuracy. The validated model was then used to simulate the annual performance of the solar LDAC in Toronto, Ontario; Vancouver, British Columbia; and Miami, Florida. The highest performance was achieved in Miami, where an overall thermal COP of 0.48 was predicted.
It is proposed that additional improvements be made to the system by replacing inefficient pumps and fans, adding desiccant storage, and improving the control scheme.

▼ M.Eng.
The need and problem was originated from the trends of the earths dwindling energy resource. As time progresses humans are becoming more aware of need to use so called “alternative energy sources” to alleviate the main energy converters i.e. power stations. The student was tasked with investigating the thermal performance of a solar powered refrigeration cycle (prototype) that could: produce enough refrigeration effect that it replaces the standard home vapour compression unit, used for cooling or freezing of foods, heats up a geyser sufficiently to have hot water for a common house hold, has excess energy to heat or cool liquid or air based environments and has the potential to lower the electrical bill of a house. The introductory step was to obtain the thermo fluid properties of aqua ammonia solutions. A setback came about when determining the aqua ammonia properties. There were too many conflicting properties being yielded by six different authors. In an attempt to gain confidence in only one author a comparison table was prepared. The table compared the six authors to each other. By looking at all the values compared it brought great clarity to the problem. When continuing the research into the fundamental law approach of solving for the cycle new findings were made. Initially very little comprehensive studies were done which explained in fundamental laws to solve for the absorption cycle. After extensive reviewing of a detailed study on how to solve for absorption refrigeration cycles, then it was able to begin improving on the thermo – fluid design of the cycle. As cycle and component design began to progress the train of thought began to steer in a direction. Each component needed to be detail designed. The advantage of having each component specifically catered for in the cycle design was that it would increase the cycle efficiency. In this way it would ensure that during the concept generation phase the functioning of each component was clear, thereby enabling a clear understanding of how components would compliment each other in a cycle. A mode of solving for the cycle was to endeavour that all parameters could be calculated unambiguously, with the aid of computerisation. Testing was carried out on a real life commercial thermal siphoning machine in order to realistically understand how absorption refrigeration works and gain experience. At the end of the study the most important result is that the dissertation research shows strong evidence that it will be possible to create a device which can fulfil the four tasks listed above. Another result is a program which is a refined cycle design of the pump absorption type refrigeration. The program solves for points along the cycle. Lastly it was found that even though EES was the simpler program to use for aqua ammonia solution properties it was the only program which catered for sub cooling and super heating.

▼ The main aim of this project is to develop an ESES lab on a full scale system. The solar combisystem used is available most of the time and is only used twice a year to carry out some technical courses. At the moment, there are no other laboratories about combisystems. The experiments were designed in a way to use the system to the most in order to help the students apply the theoretical knowledge in the solar thermal course as well as make them more familiar with solar systems components. The method adopted to reach this aim is to carry out several test sequences on the system, in order to help formulating at the end some educating experiments. A few tests were carried out at the beginning of the project just for the sake of understanding the system and figuring out if any additional measuring equipment is required. The level of these tests sequences was varying from a simple energy draw off or collector loop controller respond tests to more complicated tests, such as the use of the ‘collector’ heater to simulate the solar collector effect on the system. The tests results were compared and verified with the theoretical data wherever relevant. The results of the experiment about the use of the ‘collector’ heater instead of the collector were positively acceptable. Finally, the Lab guide was developed based on the results of these experiments and also the experience gotten while conducting them. The lab work covers the theories related to solar systems in general and combisystems in particular.

▼ Energy is very important in our life. Materials are essential to the realization of energy generation, conversion and storage. My thesis research is directed at the development of new nanostructured materials for effectively harvesting solar energy. It involves primarily chemistry-based bottom-up approaches, which are particularly attractive for the nanostructure synthesis due to their scalability, low cost and controllability. In particular, the low temperature hydro(solvo)thermal technique coupled with morphology conserved transformation routes was adopted for preparing many of the nanomaterials in my work since it is a facile, low cost, and environmentally benign technique amenable to large-scale production The thesis is divided into nine chapters. Chapter 1 surveys the current literature and outlines motivation and scope of the work. Chapter 2 introduces experimanet techniques. Major findings of the study are discussed in Chapters 3 through 8, with conclusions and outlooks summarized in Chapter 9. In chapter 1, I give a general introduction of this thesis on i) the significance of energy generation, mainly emphasizing on dye-sensitized solar cells (DSSCs); ii) advanced functional electrode materials for DSSCs; iii) developing strategies for preparing useful 1D and hierarchically porous nanomaterials, and most importantly, iv) the objectives of the thesis. Chapter 2 introduces experimental techniques used in my work. In chapter 3 a superstructure of meso/micro-porous single-crystalline ZnO nanoplates is created by controlled thermal decomposition of a nanoplate precursor prepared from a hydrothermal process. This unique porous nanoplate structure has proved to be an excellent candidate for constructing photoanodes of low-cost and high-performance dye-sensitized solar cells (DSSC). In Chapter 4 I report on the use of different sized TiO2 nanospindles to construct a double-layered photoanode for dye-sensitized solar cell (DSSC). One layer made of larger nanospindles serves to enhance light scattering and the other consisting of smaller nanospindles acts to increase the roughness factor for efficient dye-adsorption. The two-layer structure with size-varied, single-crystalline TiO2 nanospindles has demonstrated over 8.3% energy conversion efficiency. This was made possible by our successful large-scale synthesis of size-tunable, single-crystalline anatase TiO2 nanospindles. In Chapter 5 the work embarks upon three levels of undertaking ranging from nanomaterials synthesis to assembly and functionalization. Firstly, I have prepared size-tunable anatase TiO2 nanospindles via a hydrothermal process by using tubular titanates as self-sacrificing precursors. Secondly, I have densely dispersed the TiO2 nanospindles onto functional graphene oxides (GO) via a spontaneous self-assembly process. After annealing of the TiO2/GO hybrid nanocomposite in an NH3 gas flow, the TiO2 surface was effectively nitridated and the GO was reduced to…

Solar-thermal collectors capture solar energy and convert it into heat
energy. Several types of solar-thermal collectors have been used to
harness solar radiation in both residential, electricity generation, and
industrial settings; one class of solar-thermal collector design is the
direct-absorption solar collector (DASC). An ongoing technological
challenge in this area of science is to develop a truly widespread, coste
ective system which e ciently converts solar energy and can compete
with fossil fuel power generation. Nano
uids are a relatively new
class of
uid that o er great promise as an alternative to conventional
uids in a DASC due to their unique optical properties.
This thesis develops and analyses novel mathematical models to describe
and better understand the complicated interactions between solar
radiation absorption,
uid
ow and heat transfer within nano
uidbased
DASCs (NDASCs) in a multiphysics continuum mechanics approach
involving the use of coupled partial di erential equations. Overall,
we discuss and model six di erent NDASCs: Collector 1 is an
NDASC consisting of a nano
uid
owing through parallel-plates on
an inclined plane, Collector 2 is similar to Collector 1, but with a re-
ective base-panel, Collector 3 is an NDASC consisting of a nano
uid
owing through cylindrical pipes on an inclined plane, Collector 4
is a nano
uid-based direct absorbing parabolic trough solar collector
(NDAPSC) under laminar
ow, Collector 5 is an NDAPSC under turbulent
ow, and Collector 6 is an NDAPSC under turbulent
ow with
a time-dependent source term.

▼ PV/Thermal technology is the combination of solar thermal and photovoltaics - two mature and widely understood technologies. Combining the two technologies complicates existing standardized rating procedures and performance modeling methods. Currently a standardized performance test method does not exist for PV/Thermal (PV/T) panels. Existing and developing PV/T panels are commonly tested using separate standardized solar thermal and photovoltaic test procedures. Solar thermal performance is rated in terms of temperature difference whereas photovoltaic performance is dependent on absolute temperature level. The thermal and electrical performance of a PV/T panel is, however, coupled so performance equations derived using traditional test methods may not accurately reflect the performance of a combined PV/T panel over a wide range of conditions.
The purpose of this work was to develop an efficiency equation for a PV/T panel which can be derived from a minimal amount of empirical test data and still accurately predict its thermal and electrical performance over a wide range of conditions. To accomplish this, a quasi- 3-dimensional steady-state model of a sheet-and-tube PV/T collector was developed and used to generate a broad data set from which a simplified PV/T performance equation was developed. Using this numerically generated data set, and introducing additional coefficients into the traditional solar thermal performance characteristic, a modified PV/T efficiency equation was derived which expressed the electrical and thermal efficiency in terms of ambient temperature, incident solar irradiation and the temperature difference between the inlet fluid and the ambient. It was also shown, for the case studied, that the efficiency equation can be produced from as few as 6 data points and still accurately predicts the performance at a wide range of operating conditions. A TRNSYS [1] model was developed to demonstrate how the performance equation can be used to simulate the annual performance of a PV/T collector in a domestic hot water system. It was shown that a performance equation, derived from 6 data points, performed as well as a performance map which used over 1000 data points. The annual thermal and electrical production predicted by both models was within 1.5% of each other. The PV/T efficiency equations were also shown to perform well for a range of electrical parameters, thermal properties and substrate thermal conductivity values.
Future work is recommended to validate the PV/T performance equation using real empirically derived data for a range of collector designs.

▼ Energy storage by chemical looping steam/dry reforming is a
promising alternative for the utilization of solar energy in the
industrial and transport sectors. Efficient oxygen carriers with
a facile and scalable synthesis method are crucial to achieve
economic competitiveness for this solar thermochemical process.
In this thesis, a comprehensive overview of solar chemical
looping reforming is provided and the state of the art research
of its associated oxygen carriers is discussed. Improvement in
syngas yields and production rates in solar chemical looping
reforming were then explored via morphological and structural
enhancements of the oxygen carriers.
Firstly, the impact of ceria structural features on its syngas
production performance during two-step isothermal redox cycles
for four different nano and micro morphologies was investigated.
Highly porous flame-made agglomerates composed of small
crystalline particles were determined as the best performing
morphology with initial production rates of H2 and CO up to 167%
higher than that of commercial sub-micro ceria. Upon 10
isothermal redox cycles at 1173 K, these flame-made structures
still maintained at up to 57% faster production rates. It was
shown that the high porosity of the flame-made agglomerates was
important in inhibiting sintering and grain growth. Notably,
higher specific surface area flower-like morphologies collapsed
and densified rapidly, and exhibited the slowest kinetics. These
findings provide a robust set of structural properties to
engineer efficient materials for enhanced solar fuel production
by high temperature thermochemical cycles.
Secondly, a first-time investigation of using an earth-abundant
manganese-based oxygen carrier in solar chemical looping dry
methane reforming was demonstrated. It revealed a manganese
carbide/oxide redox cycle that resulted in high mass-specific
syngas yields and production rates when the oxygen carrier's
matrix was incorporated with fractional amount of cerium ions. In
particular, 15 times higher CO2 splitting rates than the undoped
manganese oxide, and also 8 times higher CO yields than cerium
oxide was achieved. The long-term performance with 100 cycles
revealed that this is not a short-lived enhancement and that the
synergetic contribution by cerium ions were highlighted. A
thorough investigation of this manganese carbide/oxide redox
mechanism was experimentally pursued further with a series of
custom-synthesized Ce-Mn oxygen carriers via solar chemical
looping steam methane reforming cycles. Interesting discoveries
of 3% Ce suggest the intense surface distribution of ceria-rich
nanoparticles that efficiently dissociate the chemisorbed species
into H2 and CO during methane reforming and water splitting.
Additionally, the abundance of Ce ions in the bulk lattice
effectively unlock…

▼ Solar photovoltaic energy technology is increasingly implemented in response to continuously growing global energy needs. While legacy technology utilizing silicon has captured much of the market, thin-film solar modules are projected to rise particularly in the U.S. production sector. Current materials utilized in production and deployment encounter resource and environmental impact constraints. This research investigates the viably controllable synthesis of multi-crystalline copper bismuth sulfide for potential use as an absorber layer in thin-film solar cells and early investigation of thin-film growth parameters which may enable a cost-effective route to full scale production of epitaxial copper bismuth sulfide films. The first step of this investigation has entailed a novel route for the solvo-thermally grown Cu3BiS3 films facilitated by L-cystine as a sulfur donating and complexing agent. In the characterization of the nanoparticulate product UV-VIS spectra were analyzed via the Tauc method of bandgap interpolation. The validity of the Tauc method in application to polycrystalline films has been investigated and proven to be robust for the material class. This justifies the bandgap assessment of the subject material and provides support for wider use of the method. With the synthesis method established, the reaction was transferred to a custom built continuous flow reactor to explore this process and help understand its capabilities and limits with respect to producing single layers for an eventual photovoltaic cell stack. Though the published work has established novel chemistry, the need to deposit and/or grow a functional p-type layer for further characterization and eventual device incorporation is key to the material evolution. First evidence of continuous flow micro-reactor deposition of Cu3BiS3 has been shown with an array of resulting microstructures. The grown microstructures are evaluated with relevance to prior synthesis laboratory procedure and recommendations are made for continuing the pursuit of a functional Cu3BiS3 coating mediated by L-cystine in a continuous flow micro-reactor.

▼ Este trabalho propõe caracterizar a complementaridade espacial-temporal entre energia eólica e solar fotovoltaica entre regiões do Brasil e estudar, no âmbito da comercialização de energia elétrica no Setor Elétrico Brasileiro - SEB, se um portfólio formado por estas fontes trazem vantagens econômicas relevantes para o investidor. Para atender a estes objetivos, foram estudados métodos para tratamento dos dados como a correção da irradiância solar, cálculo da energia gerada pelas fontes estudadas, o ambiente de contratação de energia elétrica no Brasil, métodos de otimização e modelos de análise de risco para contratação de energia no mercado livre de energia. A metodologia proposta para responder as questões colocadas foi aplicada em um estudo de caso envolvendo três regiões brasileiras em um horizonte de dez anos. Concluiu-se que existe a complementaridade energética entre as fontes nas diferentes regiões estudadas e em diferentes períodos de tempo. Confirmou-se que tecnicamente pode-se reduzir a oscilação na geração de energia analisando as fontes de forma complementar, porém, o custo de instalação da fonte fotovoltaica ainda é muito alto, inviabilizando até o momento investimentos em larga escala e de forma complementar a fonte eólica. Também verificou-se, dentro dos locais avaliados, que somente um dos três locais apresentou benefício econômico-financeiro com a formação de portfólio das fontes eólica e solar atuando no mercado de venda de energia e atendendo os critérios de risco limite estabelecidos quando avaliadas segundo a ótica da maximização da receita no mercado livre.
This thesis proposes to characterize the spatial-temporal complementarity between wind and solar photovoltaic energy between regions of Brazil and study, in the marketing of electricity in the Brazilian Electrical Sector - SEB, a portfolio formed by these sources bring significant economic benefits to the investor. To meet these goals, methods for data processing were studied as correction of solar irradiance calculation of the energy generated by the sources studied, the environment of contracting electricity in Brazil, optimization methods and models for risk analysis for contracting energy in the free energy market. The proposed methodology to answer the questions was applied in a case study involving three Brazilian regions with a horizon of ten years time series. It was concluded that there is complementarity between energy sources in the different regions studied and in different time periods. It was confirmed that technically can reduce the fluctuation in power generation by analyzing the complement of sources, however, the installation cost of photovoltaic power is still too high, preventing yet large-scale investments and complementary way the source wind. Also it was found within the sites evaluated, only one of the three sites presented economic and financial benefit by the portfolio of wind and solar sources acting in the sale of energy market and considering the risk criteria limit established when evaluated according to…

▼ The United States' energy consumption through fossil-fueld means of transportation accounts for almost one third of the global energy consumption of the transporation sector. As a consequence thereof, environmental pollution is increasing rapidly, especially CO2 emissions. This development demands reduced environmental pollution based on the introduction of less energy-consuming means of transportation. The methodological approach taken in this research provides a solar-powered tricycle design as a sovereign mode of transportation to mitigate the problem of environmental pollution through transporation. A design for a sustatinable solar-powered tricycle is presented that is expected to be able to lesson the effect of CO2 emissions, increase occupancy rates, and reduce the need for fossil fuels. The dimension of the solar-powered tricycle was determined based on torque, power, drag and aerodynamic forces, solar irradiance, and travel range. The solar-powered tricycle was built and tested in order to evaluate the practicability and feasibility of the proposed design. The overall lifecycle of the design and environmental pollutions during the manufacturing and disposal phase of the tricycle and its components were evaluated using SolidWorks Sustainability software. The annual costs of CO2 emissions, design and installation, annual maintenance, and costs to store the power for full charge, account for $417. With its travel range of 37.1km from one full charge, the proposed solar-powered tricycle can cover more than 90% of all trip distances in the USA. The proposed solar-powered tricycle can be an alternative mode of transporation that reduces energy consumption by more than 41%, as well as decreases CO2 emissions by more than 75%, in comparison with other modes of transporation like cars or railroads.

▼ Renewable
energy is the path for a sustainable future. The development in this field is progressing rapidly and
solar energy is at the heart of this development. The performance and efficiency limitations are the main obstacles preventing
solar energy from fulfilling its potential. This research intends to improve the performance of
solar panels by identifying and optimizing the affecting factors. For this purpose, a mechanical system was developed to hold and control the tilt and orientation of the photovoltaic panel. A data acquisition system and electrical system were built to measure and store performance data of the photovoltaic panels. A design of experiments and response surface methodology were used to investigate the impact of these factors on the yield response as well as the output optimization. The findings of the experiment showed an optimum result with a tilt of 60º from the horizon, an azimuth angel of 45º from the south and a clean panel condition. The wind factor showed insignificant impact within the specified range. This work can be continued by investigations on the materials, geometry, cleaning and cooling systems, and involving some other environmental and physical factors.
