Description

A rotary tracking photovoltaic power generation device

technical field

The utility model relates to the technical field of photovoltaic power generation, in particular to a rotation tracking photovoltaic power generation device.

Background technique

The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. When a photon irradiates a metal, its energy can be completely absorbed by an electron in the metal. The energy absorbed by the electron is large enough to overcome the internal gravity of the metal to do work, escape from the surface of the metal, and become photoelectrons. Silicon atoms have four outer layers. Electrons, if pure silicon is doped with atoms with five outer electrons, such as phosphorus atoms, it becomes an N-type semiconductor. If pure silicon is doped with atoms with three outer electrons, such as boron atoms, a P-type semiconductor is formed. When the P-type and N-type are combined, a potential difference is formed on the contact surface, which becomes a solar cell. When sunlight hits the P-N junction, the holes move from the N-pole region to the P-pole region, and the electrons move from the P-pole region. Move to the N pole region to form a current.
