The various applications of solar cells are described in this insightful book. Since the last decade, photovoltaic (PV) technology has shown the capability to become an extensive source of power generation for the world - with continuous and powerful growth even during times of financial and economic crisis. This growth is believed to continue in the years ahead as the awareness of the benefits of PV expands worldwide. This book discusses a wide range of modern research issues in solar cell physics and technology areas. The already established 1st generation silicon solar cell technology, the 2nd generation thin film and the 3rd generation dye sensitized solar cells, including new technologies are discussed in this book.
