Chinese Trina Solar Co. Ltd. announced that its State Key Laboratory (SKL) of PV Science and Technology (PVST) of China has set a new world record of 24.58 percent for a high-efficiency n-type mono-crystalline silicon (c-Si) i-TOPCon solar cell. The bifacial solar cell was fabricated on a large-sized 244.62 square centimeter wafer with a low-cost industrial process of advanced i-TOPCon (Industrial Tunnel Oxide Passivated Contact) technologies, having a front boron emitter and a rear full-area passivating contact. According to the company, the result has been independently confirmed by the ISFH CalTeC in Germany.
