Improvements to the technology are proceeding at an impressive pace. The CEA and 3SUN had already presented first-class results in April 2022 with 24.9%, then in December 2022 with 25.8% and 26.5% in March 2023, for the same PIN architecture tandem cell on 9cm² with shading correction.
The 9 cm² device has a Voc above 1900 mV.
The race for PIN-architecture Si/PK tandem cells with efficiencies over 30% on large surfaces is in full gear. The teams look forward to presenting further exciting results.
Stay tuned!
