PERC (Passivated Emitter Rear Cell) - emitter and back passivated battery technology. The difference from conventional batteries is the back. PERC cells use a passivation film to passivate the back, replacing the traditional all-aluminum back field to enhance light. The internal back reflection on the silicon base reduces the recombination rate on the back side, thereby increasing the efficiency of the battery by 0.5%-1%.
