The cell is generally divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon solar cell is one of the fastest developed solar cells at present. Its structure and production process have been finalized, and the products have been widely used in space and ground. The solar cells are made of high purity monocrystalline silicon rods.

In the future, TOPCon cells will also be better used in large-scale industrial production, and will gradually replace the current PERC cells; in terms of efficiency, they will gradually approach the theoretical limit of silicon-based solar cells. In addition, the full-area passivation of TOPCon cells can also be well combined with perovskite cells to form tandem cells, which will become an important way to improve the efficiency of solar cells in the future.
