After polishing, cleaning and other processes, the silicon wafers are made into raw silicon wafers to be processed. To process solar cells, the silicon wafers must first be doped and diffused. Generally, the dopants are trace amounts of boron, phosphorus, antimony, etc. The diffusion is carried out in a high-temperature diffusion furnace made of quartz tubes, so that a P>N junction is formed on the silicon wafer. Then, the screen printing method is used to print the finely prepared silver paste on the silicon wafer to make the grid line. After sintering, the back electrode is made at the same time, and the surface with the grid line is coated with an anti-reflection source to prevent a large number of photons from being reflected by the smooth silicon wafer surface. Therefore, the monomer of the single crystal silicon solar cell is made;
