Trina Claims Record for Solar Cell Efficiency

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
