Sulfide and Selenide based materials for Emerging Applications

Sulfide and Selenide based Materials for Emerging Applications addresses a materials and device approach to the transition to low cost sustainable thin film photovoltaic devices and energy storage systems. It is divided into 5 parts. Part 1 surveys the recent technological developments in kesterite film. Different synthesis methods and optical properties of the kesterire are covered to design the kesterite film for energy harvesting and storage technology. Chapters in part 1 discuss the latest research on dopant incorporation into CZTS including the effect of dopants on optical, electrical and structural properties on the kesterite. In section 2, thin film solar cells with earth abundant materials are discussed. The application of doped CZTS for earth abundant thin film solar cells and novel device structures is covered. In addition, emerging sulphide semiconductors with promising potential in thin film photovoltaics/flexible devices will be covered. There is focus on the interface engineering at the back contact of CZTS thin film solar cells. The use of various ultrathin intermediate layers with the ability to block the diffusion and reaction of Mo with CZTS is discussed. Emphasis is on the blocking mechanism; the effect of the intermediate layer on the absorber layer and the photovoltaic properties of the CZTS device. Section 3, covers the sulfur and selenides based materials for thermos-electric application. Part 4 of this book is concerned with chalcogenide semiconductors with applications in electrochemical water splitting. Pyrite and kesterite semiconductors which are earth abundant and have emerged as a promising class of nanoscale electro-catalyst material for the splitting of water into hydrogen and oxygen. The most recent developments in kesterite and pyrite semiconductors for electrochemical water splitting are surveyed. Part 5 discusses recent developments of storage technologies including Li-S batteries, sulfide based super-capacitors, and hydrogen storage. This book will be a useful resource for those involved in green energy technology and decarbonization and is designed for a broad audience, from students to the experienced scientist.
