Fraunhofer ISE showcases 24% efficient TOPCon cell, using M10 silicon wafers

German research organisation Fraunhofer ISE has developed a tunnel oxide passivated contact (TOPCon) solar cell with an efficiency of 24% using large-area M10 silicon wafers. The cell was presented at the Photovoltaic Technology Advisory Board meeting. The industry is shifting towards larger wafer sizes for better efficiency and cost-effectiveness despite silicon oversupply affecting prices.
