Photovoltaic solar energy is a new type of electricity generation system that uses the photovoltaic effect of semiconductor materials in solar cells to directly convert the energy from solar radiation into electrical energy. Solar power generation is divided into solar thermal power generation and photovoltaic power generation. Generally speaking, the generation of solar energy is also called photovoltaic. Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key element of this technology is the solar battery. Once the solar cells are connected in series, they can be packaged and protected to form a large area solar cell module and then combined with power controllers and other components to form a photovoltaic power generating device.
