Trina Solar, provider of PV and smart energy total solutions, today announced that its State Key Laboratory (SKL) of PV Science and Technology (PVST) 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. This announcement follows another similar record announcement earlier this year.

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 square centimetre 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.

This a the new world record

“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”, said Dr Zhiqiang Feng, Director of Trina Solar’s State Key Laboratory of PV Science and Technology. “The excellent R&D results lays a solid foundation for Trina to provide new differentiated PV modules and solutions to our customers.” (mfo)
