Solar photovoltaic (PV) technology is one of the most matured and field-proven technology among different renewable energy technologies. This chapter is planned to give a comprehensive introduction to PV technology and provides the necessary technical knowledge for understanding of this technology. It encompasses classification of solar PV technology and the manufacturing processes involved in various PV technology. Each part constitutes specifically an independent learning entity where the technology has been reviewed in detail. Traditional solar cell technology such as single-crystal silicon technology as well as newer technologies have been described. The chapter also covers the comparative assessment of different PV technologies in terms of its efficiency, advantages and disadvantages, etc.
