Researchers on the Nationwide Photo voltaic Vitality Institute (INES) in France – a division of the French Various Energies and Atomic Vitality Fee (CEA) – and Italian renewables specialist Enel Inexperienced Energy claims to have achieved an influence conversion effectivity of 26.5% for 2 terminal tandem perovskite-silicon photo voltaic cells. The scientists mentioned the brand new consequence improves on the 25.8% effectivity they achieved for a similar sort of cell in December 2022.
“The system with an energetic space of 9 cm² has an open circuit voltage of greater than 1,880 mV,” says CEA-INES, saying that the event of the system, which is predicated on a pin configuration , additionally resulting from “correction of shading.” It doesn’t reveal any further technical particulars.
Enel Inexperienced Energy 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 facility at present below building in Catania, southern Italy. It not too long ago mentioned that it may end up in 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 achieve 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 score of 24.47% for a gallium-doped p-type heterojunction silicon photo voltaic cell in March 2022.
In August 2020, they achieved an effectivity of 25.0% for a heterojunction photo voltaic cell with an energetic floor of 213 cm2, primarily based on an M2 silicon wafer format. With this consequence, each events improved on their earlier file of 24.63%. The tactic is predicated on heterojunction processes developed between Enel and INES, utilizing manufacturing gear offered by Meyer Burger in Switzerland.
