Thin-Film Solar Cells: Next Generation Photovoltaics and Its Applications [Paperback]

The first comprehensive book on thin-film solar cells, potentially a key technology for solving the energy production problem in the 21st century in an environmentally friendly way. It covers a wide range of scientific and technological aspects of thin film semiconductors - deposition technologies, growth mechanisms and the basic properties of amorphous and nano-crystalline silicon - as well as the optimum design theory and device physics of high-efficiency solar cells, especially of single-junction and multi-junction solar cells. The development of large-area solar cell modules using single and multi-junction solar cells is also considered. Examples of recent photovoltaic systems are presented and analysed.

The development of clean energy resources as alternatives to oiI has become one of the most important challenges for modern science and technology. The obvious motivation for these efforts is to reduce the air polIution resulting from the mass consumption of fossil fuels and to protect the ecological cycles of the biosystems on Earth. Analyses of future energy usage envision that the energy structure in the 21st century will be characterized as a Best Mix Age involving different renewable energy forms. Among the wide variety of renewable energy projects in progress, photo? voltaics is the most promising as a future energy technology. It is pollution? free and abundantly available everywhere in the world, even in space, and can also operate with diffuse light. However, a major barrier impeding the devel? opment of large-scale bulk power applications of photovoltaic systems is the high price of solar cell modules. Therefore, reduction of the costs of solar celIs is of prime importance. To achieve this objective, tremendous R&D efforts have been made over the past two decades in a wide variety of technical fields ranging from solar-cell materials, cell structure, and mass production pro? cesses to the photovoltaic systems themselves.
