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 renewable 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 stated the brand new consequence improves on the 25.8% effectivity they achieved for a similar sort of cell in December 2022.
“The machine with an lively space of 9 cm² has an open circuit voltage of greater than 1,880 mV,” says CEA-INES, saying that the event of the machine, which relies on a pin configuration , additionally because of “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 presently underneath development in Catania, southern Italy. It lately stated 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 achieve efficiencies of round 30%.
CEA-INES and Enel Inexperienced Energy are collectively growing DC/DC most energy level trackers (MPPT). They are saying they’re additionally presently 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 lively floor of 213 cm2, primarily based on an M2 silicon wafer format. With this consequence, each events improved on their earlier document of 24.63%. The tactic relies on heterojunction processes developed between Enel and INES, utilizing manufacturing tools supplied by Meyer Burger in Switzerland.
