Bifacial TOPCon solar cell with 23.84% efficiency, 90% lower silver consumption

Bifacial TOPCon solar cell with 23.84% efficiency, 90% lower silver consumption Developed by Germany’s Fraunhofer ISE, the cell is manufactured with metallization based on a plating process. The device was built with galvanic nickel/copper/silver contacts instead of common silver contacts. Researchers at Germany’s Fraunhofer Institute for Solar Energy Systems ISE have been seeking for several years to …

Large-area bifacial TOPCon solar cell with 23.01% efficiency

Large-area bifacial TOPCon solar cell with 23.01% efficiency The n-type cell was built with phosphorus-doped LPCVD poly-Si passivating contacts and achieved a remarkable open-circuit voltage of 691.7 mV. According to its creators, with some adjustments the cell may be suitable for commercial production. An international research group has fabricated a large-area bifacial TOPCon solar cell with passivating contacts …
