Atomic-Scale Insights into Emergent Photovoltaic Absorbers

This book presents an original investigation into alternative photovoltaic absorbers. Solar power is a highly promising renewable energy solution; however, its success is hampered by the limited cost-effectiveness of current devices. The book assesses the photovoltaic performance of over 20 materials using state-of-the-art, first-principles methods. Adopting a computational approach, it investigates atomic-scale properties at a level of accuracy that is difficult to achieve using laboratory-based experimental techniques. Unlike many theoretical studies, it provides specific advice to those involved in experimental investigations. Further, it proposes directions for future research.

This book advances the field of photovoltaics in three crucial ways: firstly, it identifies why one class of proposed materials cannot achieve high efficiency, while at the same time gaining insights that can be used to design future absorbers. Secondly, it shows that poor performance in the bismuth chalcohalides is not due to fundamental limitations, and can be overcome by finely controlling synthesis conditions. Lastly, it describes a range of new stable materials that are expected to show excellent photovoltaic performance.

Nominated as an outstanding PhD thesis by the University College London, United Kingdom Provides an excellent introduction to the field of photovoltaics Describes the analysis of cutting-edge photovoltaics to provide insights into the solar materials of the future Offers a crash course in the latest developments of this emerging field by examining over 20 materials Includes specific advice for experimental groups, highlighting how theory can be used to optimize photovoltaic materials
