Solar cells are connected in series and then are packaged and protected to form a large-area solar cell module, and then a photovoltaic power generation device is formed by matching with components such as a power controller and the like, wherein the main principle of photovoltaic power generation is the photoelectric effect of a semiconductor. 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 a P-N junction, current flows from the P type side to the N type side to form current, and the photoelectric effect is the phenomenon that the illumination causes potential difference between different parts of an uneven semiconductor or the combination of the semiconductor and metal. Firstly, converting photons (light waves) into electrons, and converting light energy into electric energy; second, a voltage forming process.
