Chint Solar’s sister company has been researching the technology since 2020 and built its pilot R&D line in Haining, Zhejiang, with TOPCon cells produced having reached a 24.6% efficiency rate according to Astronergy.

The products are to be unveiled formally at an event held tomorrow (26 April 2022).

Along with heterojunction, TOPCon is one of the leading candidates for next-generation technologies to help pass through p-type’s 25% efficiency rate and solar manufacturers are expecting strong shipment share for TOPCon in 2022.

Earlier this year, PV Tech’s head of market research Finlay Colville revealed which manufacturers would lead the PV industry’s transition from p-type to n-type.
