A technically authoritative overview of photovoltaics and its practical applications. This book provides an overview of PV covering areas including: a brief history of PV and the current international scene; the scientific principles of solar cells including silicon and new thin-film varieties; PV modules and arrays; grid-connected PV, from home systems up to large power plants; the wide diversity of stand-alone PV systems, and; the economic and environmental aspects of solar electricity. Since the book’s 1st edition publication in 2010, PV has progressed substantially, with a huge increase in global installed capacity. This new edition reflects on recent trends, paying particular attention to developments in grid-connected systems. Newly revised chapters expand on previous material, whilst content on CIS has been replaced by CIGS and Organic PV is introduced for the first time.
