Book Description
This book provides a comprehensive overview on fully thermal and hybrid solar generators based on thermoelectric devices. The book fills a gap in the literature on solar conversion and thermoelectrics, because despite the growing number of papers dealing with the use of thermoelectrics in solar power conversion, no book exists for PV specialists or thermoelectricity experts to enter this field. The book is intended as a primer for scientists or engineers willing to complement their expertise in one of the two fields, and to get an updated, critical review of the state of the art in thermoelectric solar harvesting.

Book Description
This Spotlight describes energy harvesting using a hybrid concentrating photovoltaic (PV) system with simultaneous thermal generation for energy storage. Several designs have been proposed to build a system that takes advantage of the entire solar spectrum through direct electric generation using concentrated light onto photovoltaics while generating thermal energy using wavelengths of light not captured by the PV cell. This eBook addresses the current technologies and state-of-the-art designs, as well as the methodologies, underlying physics, and engineering implications.

Book Description
Silicon is an abundant element and is produced in large quantities for the electronic industry. The falling price of this commodity also feeds the growth of solar photovoltaics (PV). However, solar cells (SCs) based on bulk semiconductors have quite limited maximum attainable performance. Therefore, new principles and materials are being investigat

Book Description
An integrated hybrid photovoltaic-thermoelectric system has been developed using multiple layers of organic photosensitizers on inorganic semiconductors in order to efficiently convert UV-visible and IR energy into electricity. The hot anode of n-type ZnO nanowires was fabricated using a thermal process on pre-seeded layer and results to be crystalline with a transmittance up to 92 % and a bandgap of 3.32 eV. The visible-UV light-active organic layer was deposited between the anode and cathode at room temperature using a layer-by-layer deposition onto ITO and ZnO and Bi2Te3 nanowires from aqueous solution. The organic layer, a cooperative binary ionic (CBI) solid is composed of oppositely charged porphyrin metal (Zn(II) and Sn(IV)(OH- )2) derivatives that are separately water soluble, but when combined form a virtually insoluble solid. The electron donor/acceptor properties (energy levels, band gaps) of the solid can be controlled by the choice of metals and the nature of the peripheral substituent groups of the porphyrin ring. The highly thermoelectric structure, which acts as a cold cathode, is composed of p-type Bi2Te3 nanowires with a thermoelectric efficiency (ZT) between ~0.7 to 1, values that are twice that expected for bulk Bi2Te3. Lastly, efficiency of the integrated device, was found to be 35 at 0.2 suns illumination and thermoelectric properties are enhanced by the charge transfer between the CBI and the Bi2Te3 is presented in terms of photo- and thermogenerated current and advantages of the low cost fabrication process is discussed.

Book Description
This book chronicles a few approaches to constructing biohybrid devices using photosynthetic protein complexes. Can the abundantly available solar energy be tapped to meet our rising energy demands using green and cheap active materials? Exploring nature’s own tiny solar factories, the photosynthetic proteins could hold the key. Photosynthetic pigment-protein complexes found in plants and certain types of bacteria transduce sunlight into biologically useful forms of energy through a photochemical charge separation that has a 100% quantum efficiency. Getting the photoproteins to perform this efficient energy conversion reaction in a semi-artificial setup is central to developing biohybrid solar technologies, a promising green alternative to today’s photovoltaics. This book looks into the existing challenges and opportunities in the field of biohybrid photovoltaics and provides a few prospective methods of enhancing the photocurrent and photovoltage in these devices. The book targets the readership of students, academics, and industrial practitioners who are interested in alternative solar technologies.

Book Description
Although photovoltaics are regarded by many as the most likely candidate for long term sustainable energy production, their implementation has been restricted by the high costs involved. Nevertheless, the theoretical limit on photovoltaic energy conversion efficiency-above 85%-suggests that there is room for substantial improvement of current commercially available solar cells, both silicon and thin-film based. Current research efforts are focused on implementing novel concepts to produce a new generation of low-cost, high-performance photovoltaics that make improved use of the solar spectrum. Featuring contributions from pioneers of next generation photovoltaic research, Next Generation Photovoltaics: High Efficiency through Full Spectrum Utilization presents a comprehensive account of the current state-of-the-art in all aspects of the field. The book first discusses topics, such as multi-junction solar cells (the method closest to commercialization), quantum dot solar cells, hot carrier solar cells, multiple quantum well solar cells, and thermophotovoltaics. The final two chapters of the book consider the materials, fabrication methods, and concentrator optics used for advanced photovoltaic cells. This book will be an essential reference for graduate students and researchers working with solar cell technology.
