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