Available in PDF, EPUB and Kindle. Book excerpt: Discover the latest techniques and applications for solar energy concentrators in this essential guide for academics, researchers, environmentalists, and professionals seeking to harness the power of solar energy while reducing environmental impact and costs. This book is centered on contemporary fundamental techniques for collecting solar radiation and the prospective applications that show how solar energy concentrators (SEC) can be used in a variety of systems and may provide significant economic and environmental benefits. Around the globe, there is a tremendous drive to investigate the viability of utilizing solar energy, particularly in regions with temperate zones. The usage of solar energy in many sectors has grown over the years. The ongoing quest for an alternate energy source in response to the apparent depletion of fossil resources is the driving factor behind this transition. Fossil fuels are far more widely used now than ever before despite their rising price. Although all forms of renewable energy are accessible, solar radiation is the most prevalent and easily accessible. Using solar energy for higher processing temperatures is difficult despite being the most common clean and affordable renewable energy source on the planet. For this, solar energy concentrators (SEC) are a promising technology that could be used to harness both heat and electricity for diversified industrial operations. SECs are devices that harvest solar radiation and direct it to a single point of concentration. This book presents the most up-to-date fundamental strategies for the collection of the sun’s radiation. Moreover, SEC technical summaries are also evaluated concerning ongoing international assignments. Prominent applications are also featured to show the reader the scope of the SEC’s applicability. The potential implementations demonstrate that CSE can be employed in a wide range of systems and may offer considerable economic and environmental advantages.

Indeed, the applications of solar energy are manifold, primarily because it concerns both light and heat. Photovoltaic (PV) conversion is the most well-known among these, but other modes of conversion include photochemical, photobiological, photoelectrochemical, thermal and thermochemical. This book covers the entire chain of conversion from the Sun to the targeted energy vector (heat, electricity, gaseous or liquid fuels). Beginning with the state of the art, subsequent chapters address solar resources, concentration and capture technologies, the science of flows and transfers in solar receivers, materials with controlled optical properties, thermal storage, hybrid systems (PV-thermal) and synthetic fuels (hydrogen and synthetic gas). Written by a number of experts in the field, Concentrating Solar Thermal Energy provides an insightful overview of the current landscape of the knowledge regarding the most recent applications of concentrating technologies.

Download or read book Photon enhanced Thermionic Emission for Concentrated Solar Energy Harvesting written by Jared William Schwede and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional conversion of sunlight into electricity usually takes one of two forms: a "quantum" approach using the large energy of solar photons in photovoltaic (PV) cells, or a "thermal" approach using solar radiation as the heat source in a classical heat engine. Quantum processes boast high theoretical efficiencies as the effective solar photon temperature is ~6000 K, yet suffer in practice from a limited spectral energy collection window and thermalization losses. Thermal processes take advantage of energy throughout the entire spectrum, but efficiency is curbed by practical operating temperatures. Combinations of the two are predicted to have efficiencies above 60%, yet are difficult in practice because PV cells rapidly lose efficiency at elevated temperatures, while heat engines rapidly lose efficiency at low temperatures. As a result, these two approaches have remained disjointed. In this work, I describe a novel method of solar energy conversion called Photon-Enhanced Thermionic Emission (PETE), which uses photoexcitation in a hot semiconductor in conjunction with thermionic emission to generate electricity. By combining this quantum and thermal process, devices based on PETE can in principle exceed the Shockley-Queisser limit on single-junction photovoltaics, and furthermore can potentially operate at temperatures compatible with solar thermal conversion systems, enabling a two-stage cycle with very high theoretical efficiency. After explaining the theoretical potential of PETE devices, I describe the experimental demonstration of the PETE effect. However, these proof-of-concept measurements are seen to display very low performance, quite disconnected from our idealized theoretical modeling. I therefore introduce more detailed analytic models for the PETE process which include carrier diffusion and non-ideal recombination. Using these models, I describe a GaAs/AlGaAs heterostructure which improves efficiency by introducing an internal interface, decoupling the basic physics of PETE from the vacuum emission process and protecting photoexcited electrons from the vacuum interface. The heterostructure is shown to dramatically improve performance, and with further work could form a realistic basis for practical PETE devices.
Download or read book Spectral and Spatial Tuning of Absorption for Enhanced Solar Energy Conversion written by Nicholas P. T. Sergeant and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for sustainable energy resources has emerged as one of the most significant and universal concerns society will face in the 21st century. Solar energy conversion offers a cost-effective alternative to our traditional greenhouse gas emitting power plants. The most common solar energy conversion processes are solar photovoltaic conversion and solar photothermal conversion. In the first one, solar photons are converted directly into electrical energy, whereas in the latter solar photons are converted into heat. The heat can then be converted into electrical energy by a steam turbine or a thermophotovoltaic cell. In both types of solar energy conversion it is of outmost importance to optimize the absorption process by maximizing the trapping of solar photons inside the photoactive absorber, while minimizing the potential loss mechanisms, such as thermal emission in photothermal conversion or exciton recombination in photovoltaic conversion. In this dissertation coherent light trapping approaches are explored based on wave optics, thus in the regime where light needs to be treated as a wave phenomenon and can be made to interfere or diffract in order to reinforce the electric field in certain regions (spatial tuning) for a desired frequency range (spectral tuning). Photonic design can help spectrally and spatially tune the electric field distribution and consequently the absorption for a specific conversion process, device or application. In chapter 1 we first introduce the physical quantities that will be used throughout this dissertation in greater depth. This chapter covers the optical properties of materials, the physical quantities describing spectral radiance and the emissivity/absorptivity of blackbody and non-blackbody surfaces, as well as the modeling techniques used in the optimization of nanophotonic designs for enhanced absorption or spectral selectivity. In chapter 2 and chapter 3 we focus on spectrally selective absorbers and photon radiators (emitters) for concentrated solar photothermal and thermophotovoltaic applications, respectively. For both applications, spectral tuning of the absorber surface is important. An ideal solar absorber operating at elevated temperature has high absorptivity over the solar spectrum, while suppressing parasitic IR thermal emission from its surface. In chapter 2, we study the use of aperiodic metal-dielectric coatings both on planar as well as on nanostructured substrates, to achieve the desired spectral selectivity over a wide angular range. Based on our modeled results, our optimized aperiodic multilayer stacks have the potential to outperform current commercially available solar thermal coatings. Using a vacuum emissometer, an apparatus that is able to measure the spectral emission of coatings at elevated temperature, we experimentally demonstrate the excellent spectral selectivity of these aperiodic metal-dielectric solar-selective coatings for concentrated solar thermal applications. In chapter 3, we study the use of aperiodic metal-dielectric coatings as photon radiators to achieve high thermophotovoltaic energy conversion at practical temperatures of operation. In chapter 4 we review light trapping strategies for thin-film solar photovoltaic energy conversion. Thin-film solar photovoltaic devices have an enormous potential to reduce the cost of solar electricity. However, because thin photoactive layers are used, optical absorption is incomplete unless light trapping strategies are employed. Since conventional light trapping approaches, based on geometric scattering, are less effective in thin-film devices, coherent light trapping approaches that exploit the wave nature of light are reviewed that have the potential to significantly enhance optical absorption over a broad spectral range. In chapter 5 and chapter 6 we focus on thin-film organic solar cells, a thin-film technology that has great potential to reduce the cost of solar energy conversion by the use of low-cost photoactive materials and the compatibility with high-throughput roll-to-roll manufacturing. In organic photovoltaic cells, the optical absorption is incomplete unless light trapping strategies are employed. As will be shown, it is important to both spectrally and spatially tune the absorption inside the photoactive region to optimize the exciton creation and to minimize parasitic losses. Multilayer metal-dielectric stacks are investigated to enhance absorption efficiency in organic solar cells without sacrificing charge carrier collection efficiency. We have experimentally shown that these multilayer stacks can at the same time serve as a transparent contact as well as enhance photon harvesting, resulting in improved power conversion efficiency. This will be demonstrated on glass substrates in chapter 5, as well as using a roll-to-roll process on flexible substrates in chapter 6.
