Photovoltaic power generation installation price, high-quality photovoltaic power generation installation wholesale \ photovoltaic hole drilling, the main principle of photovoltaic power generation is the photoelectric effect of semiconductors. When a photon irradiates a metal, all of its energy can be absorbed by an electron in the metal. The energy absorbed by the electron is large enough to overcome the internal gravity of the metal and perform work, leaving the metal surface and escaping to become photoelectrons. Silicon atoms have outer electrons. If atoms with outer electrons, such as phosphorus atoms, are mixed into pure silicon, it becomes a type semiconductor. If atoms with outer electrons, such as boron atoms, are mixed into pure silicon, a type semiconductor is formed. semiconductor. When type and type are combined, a potential difference forms at the contact surface, becoming a solar cell. When sunlight hits the junction, holes move from polar region to polar region, and electrons move from polar region to polar region, forming an electric current. Business scope radiates
