25% Efficiency For Heterojunction Solar Cell

• CEA-INES has announced achieving 25% solar cell efficiency for HJT solar cell
• It achieved the level with its industrial partner Enel Green Power
• The efficiency was reported for active area of using M2 wafer and 213 cm² on CEA's industrial pilot line

For a heterojunction (HJT) solar cell, 25% of active area power conversion efficiency has been achieved using an M2 wafer. This 'world-class result' has been certified by ISFH CalTec.

The efficiency level was reached by the Atomic Energy Commission (CEA) at French National Solar Energy Institute (INES) and Enel Green Power (EGP) of Italy.

In a very brief statement issued, INES said the efficiency was reached on an active area of 213 cm² on CEA's industrial pilot line. It added that the developments will be shared during the next EU-PVSEC to be held in September 2020.

INES added that this 25% efficiency achieved confirms the technology roadmap developed in partnership between EGP and CEA-INES.

With this, the 2 partners have breached their previous record of 24.63% HJT solar cell efficiency, also achieved on M2 wafer using Meyer Burger production equipment as announced in February 2020 (see 24.63% Solar Cell Efficiency For Heterojunction Technology).
