Wide-Gap Chalcopyrites
Chalcopyrites, in particular those with a wide band gap, are fascinating materials in terms of their technological potential in the next generation of thin-film solar cells and in terms of their basic material properties. They exhibit uniquely low defect formation energies, leading to unusual doping and phase behavior and to extremely benign grain boundaries. This book collects articles on a number of those basic material properties of wide-gap chalcopyrites, comparing them to their low-gap cousins. They explore the doping of the materials, the electronic structure and the transport through interfaces and grain boundaries, the formation of the electric field in a solar cell, the mechanisms and suppression of recombination, the role of inhomogeneities, and the technological role of wide-gap chalcopyrites.

Copper Zinc Tin Sulfide-Based Thin-Film Solar Cells
Beginning with an overview and historical background of Copper Zinc Tin Sulphide (CZTS) technology, subsequent chapters cover properties of CZTS thin films, different preparation methods of CZTS thin films, a comparative study of CZTS and CIGS solar cell, computational approach, and future applications of CZTS thin film solar modules to both ground-mount and rooftop installation. The semiconducting compound (CZTS) is made up earth-abundant, low-cost and non-toxic elements, which make it an ideal candidate to replace Cu(In,Ga)Se2 (CIGS) and CdTe solar cells which face material scarcity and toxicity issues. The device performance of CZTS-based thin film solar cells has been steadily improving over the past 20 years, and they have now reached near commercial efficiency levels (10%). These achievements prove that CZTS-based solar cells have the potential to be used for large-scale deployment of photovoltaics. With contributions from leading researchers from academia and industry, many of these authors have contributed to the improvement of its efficiency, and have rich experience in preparing a variety of semiconducting thin films for solar cells.

Thin-Film Compound Semiconductor Photovoltaics - 2007: Volume 1012
Thin-film compound semiconductor photovoltaic solar cells have demonstrated efficiencies of nearly 20% and are leading candidates to provide lower-cost energy due to potential advantages in manufacturing and materials costs. To fulfill the promise, a number of technical issues are being addressed, including a lack of fundamental understanding of these unique materials, devices and processes for large-area deposition. This book focuses on advances in the materials science, chemistry, processing and device issues of thin-film compound semiconductor materials that are used, or have potential use, in photovoltaic solar cells and related applications. Topics include: growth and performance of compound thin-film solar cells; novel materials and processes; defects and impurities; industrial perspectives; contacts and interfaces; grain boundaries and inhomogeneities; and structural, optical and electronic characterization.
II-IV Compound Semiconductor Photovoltaic Materials: Volume 668
This book focuses on materials issues related to Cu(In,Ga)(Se,S)2 and CdTe-based polycrystalline thin-film photovoltaic solar cells and related oxides and chalcogenides. Phase equilibrium and thermochemical kinetic aspects of the absorber layer formation of CdTe and Cu(In,Ga)(Se,S)2 are emphasized and several papers on micro-analytical analysis report on detailed structural properties of thin films. The use of flexible plastic or metal foil substrates as an alternative to glass is addressed in terms of solar-cell performance and limitations imposed by the nature of the substrates. Properties of defects and interfaces in CdTe and CIGSS are highlighted using electrical, optical, and micro-analytical tools. While film properties are correlated to device physics, controversy still exists on the detailed operation of both CdTe and CIGSS devices. Topics include: materials and synthesis; thin films on alternate substrates; defects; growth and junction formation; surfaces and interfaces and film and device characterization.
Terahertz Spectroscopy
The terahertz regime of the electromagnetic spectrum was largely unexplored due to the lack of technology needed to generate and detect the radiation. However, in the last couple of decades, there has been a dramatic increase in tools needed to harness the radiation. This remarkable progress made in the development of terahertz sources, components, and detectors has resulted in an ever-increasing inquisitiveness of the applications of terahertz technology in a wide range of fields including medicine, pharmaceuticals, security, sensing, and quality assurance. This book, Terahertz Spectroscopy - A Cutting Edge Technology, presents an overview of the recent advances in terahertz technology and ...
Sustainability Science
Sustainability Science: Key Issues is a comprehensive textbook for undergraduates, postgraduates, and participants in executive trainings from any disciplinary background studying the theory and practice of sustainability science. Each chapter takes a critical and reflective stance on a key issue or method of sustainability science. Contributing authors offer perspectives from diverse disciplines, including physics, philosophy of science, agronomy, geography, and the learning sciences. This book equips readers with a better understanding of how one might actively design, engage in, and guide collaborative processes for transforming human-environment-technology interactions, whilst embracing complexity, contingency, uncertainties, and contradictions emerging from diverse values and world views. Each reader of this book will thus have guidance on how to create and/or engage in similar initiatives or courses in their own context. Sustainability Science: Key Issues is the ideal book for students and researchers engaged in problem and project based learning in sustainability science.
