The structure of the solar cell
structure of the most popular include PN junction of a semiconductor. Semiconductor cheapest and most abundant on Earth, silicon is being used to make solar cells. These silicon smelting And through a process of purification. Until a crystal Then, through the process of diffusion of impurities to create a p-n. By adding phosphorus dopants The n-type semiconductor. (Because the conductivity of electrons, which are negatively charged) and the addition of boron dopants. A p-type semiconductor. (Because the conductivity of Holstein, which are positively charged), so when the p-type semiconductor and ligaments come together. PN junction is formed. The structure of the silicon solar cells May be shaped into a circle or a square sheet thickness 200-400 microns (0.2-0.4 mm). The surface light diffusion layer has a conductivity. Electrodes front light will resemble bone to get the most exposure. The rear electrode is a full metal surfaces.
