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.
