Silver Consumption in TOPCon Solar Cells Reduced by Factor 10

Scientists at the Fraunhofer Institute for Solar Energy Systems ISE have succeeded in reducing the silver consumption of TOPCon solar cells to 1.1 milligrams per watt peak. Currently, TOPCon solar cells require an average of 10 to 12 milligrams of silver per watt peak. To the reduction, they tested an electroplating-based inline metallization process on pilot systems developed by RENA Technologies…
