Photovoltaic power generation is a technology that directly converts light energy into electric energy by using photovoltaic effect of semiconductor interface. It is mainly composed of solar panels (components), controllers and inverters, and the main components are composed of electronic components. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module, and then form a photovoltaic power generation device with power controllers and other components.

Principle: The main principle of photovoltaic power generation is the photoelectric effect of semiconductor. When a photon irradiates a metal, its energy can be completely absorbed by an electron in the metal. The energy absorbed by electrons is large enough to overcome the gravity inside the metal and escape from the metal surface to become photoelectrons. Silicon atoms have four outer 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 P-type and N-type are combined, the contact surface will form a potential difference, which will become a solar cell. When sunlight strikes the P-N junction, holes move from the P-pole region to the N-pole region, and electrons move from the N-pole region to the P-pole region, forming a current.

Photoelectric effect is a phenomenon that light causes potential difference between heterogeneous semiconductor or different parts of semiconductor and metal. First of all, it is a process from photons (light waves) to electrons, and from light energy to electric energy. Secondly, it is the process of forming voltage. Polycrystalline silicon is made into silicon wafer to be processed through ingot casting, ingot breaking and slicing. Doping and diffusing a small amount of boron and phosphorus on the silicon wafer will form a pn junction. Then, the prepared silver paste is printed on the silicon wafer by screen printing to make grid lines, and then the back electrode is made at the same time after sintering, and a layer of antireflection coating is coated on the surface with grid lines to make the battery chip.
