Image: Bert Thin Films. Kentucky-based Bert Thin Films has used a proprietary copper paste on a tunnel oxide passivated contact (TOPCon) M10 solar PV cell with a conversion efficiency of 24%.

TOPCon is one of the most promising architectures and the LECO tool is an innovative process in the race for higher-efficiency solar cells. Bert Thin Films’ approach addresses the key ...
