TOPCon Cell

As an advanced version of PERC technology, TOPCon adopts a unique tunnel oxide layer and polysilicon stacking design, which improves photoelectric conversion efficiency while perfectly compatible with existing production line equipment. Its core advantage lies in reducing charge recombination loss, especially suitable for photovoltaic power plant scenarios with dual demands for power generation efficiency and cost control. It is currently a key direction for technology iteration of mainstream manufacturers.
