The CEA at INES, ENEL Green Power and its Sicilian affiliate 3SUN have announced a new record for a PIN architecture two-terminal perovskite-silicon tandem cell with a conversion efficiency of 28.4% on 9 cm² with shading correction.
In 2023, the CEA and 3SUN have previously announced 26.5% in March, and 27.1% in June for the same type of PIN architecture tandem cell on 9cm² with shading correction. The year closes on a high note for the team, with this cell, certified by the European Commission JRC-ESTI at a conversion efficiency 24.4% equivalent to 28.4% with shading correction. Like the previous performance record, the device has an active surface area of ~ 9 cm² and a Voc of over 1900 mV.
Most of the efficiency records published internationally are for surfaces of 1cm². The team's researchers are focused on simultaneously seeking the best efficiency and stability over time, on larger surfaces, to demonstrate the feasibility of industrialization as soon as possible.
