Trina Solar said TÜV Nord in Germany confirmed the efficiency rate of its latest solar hive.
China's Trina Solar revealed that it has achieved a power conversion efficiency of 24,24% for a TOPCon n-type solar cell based on 210mm wafers. The results were confirmed by TÜV Nord in Germany.
“In March, Trina Solar achieved a maximum efficiency of 25,5% for large-area i-TOPCon 210 × 210 mm cells, setting a new world record for industrial large-area n-type i-TOPCon cells, the company said in a statement. Trina Solar researchers at the State Key Laboratory of PV Science and Technology developed multi-conductor encapsulation and innovative encapsulation technologies, along with non-destructive laser cutting technology to improve module efficiency. Using 210mm wide area i-TOPCon n-type cells, they achieved a maximum aperture efficiency of 24,24% for 600 W+ large area units with an area of 2.807 m 2 .
The manufacturer said this is the first time a unit aperture efficiency of more than 24% has been achieved with large-area i-TOPCon n-type industrial cells.
In mid-July, Trina achieved a power conversion efficiency of 24,5% for a PERC p-type solar cell based on 210 mm wafers. Those results, confirmed by the State Laboratory of PV Science and Technology in China, represented a world record for this type of cell, he claimed. As of August 2021, the hive was still yielding 23,5%, meaning it had gained 1 percentage point in less than 12 months.
In a recent interview, Helena Li, president of the company's global cell and module business, outlined plans to launch new solar units TOPCon. However, he said the entire n-type transition is now being postponed. The company now plans to increase its capacity for new n-type products from 500 MW to 20 GW by the end of 2023.
