CEA-INES, Enel achieve 27.1% efficiency for tandem perovskite-silicon solar cell – pv magazine International

Researchers on the Nationwide Photo voltaic Power Institute (INES) in France – a division of the French Various Energies and Atomic Power Fee (CEA) – and Italian renewables specialist Enel Inexperienced Energy claims to have achieved an influence conversion effectivity of 27.1% for 2 terminal tandem perovskite-silicon photo voltaic cells. The scientists mentioned the brand new outcome improved on the 26.5% effectivity they achieved for a similar sort of cell in March.

The system with an lively space of ​​9 cm² has an open circuit voltage of greater than 1,900 mV, says CEA-INES, as the development of the system is due, once more, to “shading correction. ” It didn’t reveal any additional technical particulars.

“CEA and 3SUN have already offered first-class leads to April 2022 with 24.9%, then in December 2022 with 25.8% and 26.5% in March 2023, for a similar PIN structure tandem cell,” the CEA-INES mentioned in an announcement.

Enel Inexperienced Energy via its unit 3Sun is betting on an n-type heterojunction (HJT) cell with an effectivity of 25.5% for the brand new 3 GW photo voltaic module manufacturing unit at present underneath development in Catania, southern Italy. It just lately mentioned that it can lead to module efficiencies above 24%. From 2026, Enel Inexperienced Energy plans to supply extra environment friendly photo voltaic modules primarily based on tandem silicon-perovskite cells. The ultimate merchandise are reported to succeed in efficiencies of round 30%.

CEA-INES and Enel Inexperienced Energy are collectively creating DC/DC most energy level trackers (MPPT). They are saying they’re additionally at present engaged on high-efficiency bifacial PV panels. Moreover, they declare to have achieved an influence conversion effectivity ranking of 24.47% for a gallium-doped p-type heterojunction silicon photo voltaic cell in March 2022.
