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.
