Solar photovoltaic effect, abbreviated as photovoltaic (PV), also known as photovoltaic effect (Photovoltaic), refers to the phenomenon of uneven semiconductors or the potential difference between the parts of the combination of semiconductors and metals when illuminated.
Photovoltaics is defined as the direct conversion of ray energy. In practical applications, it usually refers to the conversion of solar energy to electrical energy, that is, solar photovoltaic. Its realization is mainly through the use of solar panels made of silicon and other semiconductor materials, and the use of light to generate direct current, such as solar cells that can be seen everywhere in our daily lives.
Solar power generation is an emerging renewable energy technology. The industrialized applications are mainly solar photovoltaic power generation and solar thermal power generation. The photovoltaic power generation industry chain from upstream to downstream includes polysilicon, silicon wafers, and batteries. Wafers and battery components, and monocrystalline furnaces are important equipment in the solar photovoltaic power generation industry. With the rapid growth of my country's photovoltaic industry, the scale of the industry has grown steadily, and solar cells are developing towards ultra-efficient cell technologies such as N-type double-sided, heterojunction, and half-cell. Single crystal silicon with low oxygen and carbon content and high conversion efficiency becomes necessary. This is inseparable from the strong support of the single crystal silicon manufacturing key equipment-single crystal furnace.
