Technical Field

Background

The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. When photons irradiate on the metal, the energy of the photons can be completely absorbed by certain electrons in the metal, and the energy absorbed by the electrons is large enough to overcome the internal attraction of the metal to work, so that the photons leave the surface of the metal and escape to form photoelectrons. The silicon atom has 4 outer electrons, and if the pure silicon is doped with 5 outer electron atoms such as phosphorus atom, the silicon atom becomes an N-type semiconductor; if atoms with 3 outer electrons, such as boron atoms, are doped into pure silicon, a P-type semiconductor is formed. When the P-type and the N-type are combined together, a potential difference is formed at the contact surface, and the solar cell is formed. When sunlight irradiates the P-N junction, holes move from the N pole region to the P pole region, and electrons move from the P pole region to the N pole region to form current.
