Thin Film Photovoltaics: Single-junction and Tandem provides a comprehensive introduction to thin film solar cells and the latest developments in this expanding field. The book includes detailed information on material properties required for solar cells, working principles, energy band structure, charge transport to the electrodes and approaches to improve efficiency. Front-end and back-end processes are discussed in detail. Current challenges to commercial translation and potential opportunities to overcome to those challenges are also covered, and factors limiting solar cells parameters are also considered. Emphasis is on new materials and state-of-the-art technologies used for fabrication and characterization.

This book is suitable for researchers in academia and R&D in the subject areas of materials science and engineering, energy, physics, and chemistry.
