Laser Selective PN Junction Removal and Passivation Machine (RM-LSR-9000, Retrofitted)

RM-LSR-9000 adopts selective laser local passivation technology to precisely suppress cut edge defects and edge carrier recombination. Under the premise of low-cost production line upgrades, the power of each module is stably increased by 6–10W. It is perfectly suitable for 182/210 large-size silicon wafers and the mass production of mainstream high-efficiency cells such as TOPCon and HJT, making it the core technical modification solution for improving quality and efficiency of PV cells at this stage.
