Advanced texturing, passivation and anti-LID technologies were integrated into the PERC cell. Chinese solar cell manufacturer Sun said that it achieved a record solar cell efficiency of 22.04 % for P - type multicrystalline Passivated Emitter Rear Cells ( PERC ) . Using a high - quality high - mc - Si silicon , the 245.83 cm2 wafer beat JinkoSolar 's previous record of 22 % set last year .
