This chapter provides a comprehensive overview of the key principles underlying PV technology, exploring the fundamental concepts of solar radiation, semiconductor physics, and the intricate mechanisms that facilitate the transformation of sunlight into a usable electrical. . Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage. Below, you can find resources and information on the. . Solar energy is the radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. Photovoltaic (PV) technology, solar thermal systems, and concentrated solar power (CSP) are the primary. .
