The production of silicon solar cells is mainly based on semiconductor materials, and its working principle is that photoelectric materials absorb light energy and then undergo photoelectric conversion reaction.

When silicon crystal is doped with other impurities, such as boron, boron is stable at room temperature and can react with nitrogen, carbon and silicon, and boron can also react with many metals. Metal oxides react to form? Metal boride.

The usual crystalline silicon solar cells are made on high-quality silicon wafers with a thickness of 350 ~ 450μ m by pulling or casting. Saw marks on silicon ingots.
