CEA at INES, ENEL Green Power and its subsidiary 3SUN of Catania, are developing the tandem perovskite-silicon technology with two terminals to reach the highest industrially feasible efficiencies as soon as possible.
Their new record obtained for a PIN architecture cell is a conversion efficiency of 26.5% on 9 cm² with shading correction.
The device with an active area of 9 cm² has a Voc above 1880 mV.
Earlier records had been reached in April 2022 with 24,9%, then in December 2022 with 25.8% still with a tandem cell of PIN architecture on 9 cm² and with shading correction.
The race towards higher efficiency (>30%) Si/PK tandem cells with PIN architecture, on large surfaces and on their manufacturing processes, is going on...
