Trina Solar Records 24.58% Efficiency For Mono-Crystalline Cell

Trina Solar’s State Key Laboratory (SKL) of PV Science and Technology (PVST) of China has set a new world record of 24.58% for a high-efficiency n-type monocrystalline silicon solar cell.

Leading global PV and smart energy total solution provider, Trina Solar, has announced that its State Key Laboratory (SKL) of PV Science and Technology (PVST) of China has set a new world record of 24.58% for a high-efficiency n-type monocrystalline silicon (c-Si) i-TOPCon solar cell.

The record-breaking bifacial solar cell was fabricated on a large-sized 244.62 cm2wafer 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. The bifacial solar cell reached a total-area front side efficiency of 24.58%, without using any dedicated aperture during the illumination. This result has been independently confirmed by the ISFH CalTeC in Germany.

“We are very delighted to announce the latest achievement from our 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 two-side contact silicon solar cell,” said Jifan Gao, the CEO of Trina Solar. “The excellent R&D results lay a solid foundation for Trina to provide new differentiated high-end PV modules and solutions to our customers.”

In April, Belgian micro and nano-electronic research center Imec announced that its n-PERT (Passivated Emitter and Rear Totally diffused) solar cells developed with Chinese bifacial solar panel maker Jolywood have reached a certified and record front-side conversion efficiency of 23.2 percent.

In January, LONGi Solar achieved the new monocrystalline silicon PERC world record conversion efficiency using commercial wafer (M2) dimensions that exceed 24 percent for the first time, according to tests carried out by the National Center of Supervision and Inspection on Solar Photovoltaic Product Quality (CPVT) in China. The company’s latest breakthrough bifacial PERC solar cells tested by CPVT achieved a conversion efficiency of 24.06 percent.
