Spray passivation to reduce losses in TOPCon, HJT cell-to-module process
Chinese researchers have developed a new passivation technique for shingled solar panels based on tunnel oxide passivated contacts (TOPCon) or heterojunction (HJT) tech. It reduces recombination losses in the cell-to-module process and reportedly increases open-circuit voltage, fill factor, and efficiency.
