Trina Solar Co. Ltd. says its State Key Laboratory of PV Science and Technology of China has set a new world record of 23.22% for a high-efficiency, large-area, quasi-monocrystalline n-type (c-Si) i-TOPCon solar cell.
The record-breaking n-type bifacial i-TOPCon solar cell was fabricated with a low-cost industrial process of advanced i-TOPCon (Industrial Tunnel Oxide Passivated Contact) technologies, on a large-sized phosphorus-doped Cast-mono Si substrate.
The 247.79 cm2 bifacial solar cell reached a total-area front side efficiency of 23.22%. This result has been independently confirmed by the ISFH CalTeC in Germany.
“We are very delighted to announce the latest achievement from our technology research team at the SKL PVST. To the best of our knowledge, this is the new world record for a total-area efficiency for a large-area cast-mono silicon solar cell” says Dr. Zhiqiang Feng, director of the lab. “The excellent R&D results lays a solid foundation for Trina to provide a new differentiated high-end PV modules and solutions to our customers.”
Trina Solar focuses on PV product research and development, manufacture and sales; PV project development, operation and maintenance; smart micro-grid and multi-energy complementary system development and sales; and energy cloud-platform operation.
