Laser Etching Machine
D632B Laser Etching Machine is mainly designed for the polyfinger process of the back of TOPCon cells. By patterning and modifying the PSG film, it works in conjunction with subsequent wet process to achieve localized thinning of the back poly-Si film, thereby enhancing the efficiency and bifaciality of TOPCon cells.
