This book will guide Photovoltaics researchers in a new way of thinking about harvesting light energy from all wavelengths of the solar spectrum. It closes the gap between general solar cells books and photovoltaics journal articles, by focusing on the latest developments in our understanding of solid-state device physics. The material presented is experimental and based on II-VI thin-film materials, mainly CdTe-based solar cells. The authors describe the use of new device design, based on multilayer graded bandgap configuration, using CdTe-based solar cells. The authors also explain how the photo-generated currents can be enhanced using multi-step charge carrier production. The possibility of fabricating these devices using low-cost and scalable electroplating is demonstrated. The value of electroplating for large area electronic devices such as PV solar panels, display devices and nano-technology devices are also demonstrated. By enabling new understanding of the engineering of electroplated semiconductor materials and providing an overview of the semiconductor physics and technology, this practical book is ideal to guide researchers, engineers, and manufacturers on future solar cell device designs and fabrications. Discusses in detail the processes of growths, treatments, solar cell device fabrication and solid state physics, improving readers’ understanding of fundamental solid state physics; Enables future improvements in CdTe-based device efficiency; Explains the significance of defects in deposited semiconductor materials and interfaces that affect the material properties and resulting device performance.

Die Photovoltaik trägt als wichtiger Baustein im Mix der regenerativen Energien dazu bei, den bereits stattfindenden Klimawandel aufzuhalten und die Erde langfristig mit günstiger Energie zu versorgen. Sie fasziniert mit ihrem Prinzip, lautlos, emissions- und nahezu wartungsfrei aus dem „Nichts“ Strom zu produzieren. Als gebäudegebundene Anlage findet sie ihren idealen Einsatzort genau dort, wo der Strom benötigt wird und nutzt die ohnehin vorhandenen Flächen und Leitungen. Das Ausmaß der derzeitigen Photovoltaik-Anwendungen bleibt jedoch weit hinter ihrem Potenzial zurück, obwohl die Hersteller bereits vielfältige Techniken und Produkte anbieten. Als Gründe gelten insbesondere gestalterische, konstruktive und baurechtliche Probleme. Dieser Band der DETAIL Praxis Reihe zeigt anschaulich, wie die technische, gestalterische und konstruktive Integration der Solaranlagen am Gebäude gelingt. Das Kapitel Baurecht, ein Glossar sowie ergänzende Quellen und Verzeichnisse dienen der weiteren Vertiefung. Vorbildlich realisierte Projektbeispiele mit den unterschiedlichen Einbauvarianten an Dach und Fassade runden das Buch ab.

Photovoltaic cells provide clean, reversible electrical power from the sun. Made from semiconductors, they are durable, silent in operation and free of polluting emissions. In this book, experts from all sectors of the PV community — materials scientists, physicists, production engineers, economists and environmentalists — give their critical appraisals of where the technology is now and what its prospects are./a

Structure, Properties and Preparation of Perovskite-Type Compounds, Volume 5 presents the various methods of preparing powders, single crystals, and thin films of perovskite-type compounds. This book discusses the structure of perovskite-type compounds and their properties. Organized into 11 chapters, this volume begins with an overview of the structure, properties, and preparation of perovskite-type compounds. This text then examines how X-ray diffraction can be used to determine unit cell data and to orient single crystals. Other chapters consider the effect of nuclear radiation on the properties of ferroelectric materials. This book discusses as well the phase transitions in perovskite-type compounds, which are often associated with a change in ferroelectric properties. The final chapter explores the two techniques in the preparation of the ternary carbides with the perovskite structure, which involves melting the appropriate proportions of the two metals and carbon under argon. This book is a valuable resource for solid-state chemists.
