Recently, a paper titled “Inhibiting defect passivation failure in perovskite for perovskite/Cu(In,Ga)Se2 monolithic tandem solar cells with certified efficiency 27.35%” co-authored by NICE Low Carbon Institute and Beijing Institute of Technology was published in Nature Energy (Impact Factor: 60.1), marking a significant research breakthrough in next-generation solar cells.
The perovskite-copper indium gallium selenide (CIGS) thin-film tandem solar cell jointly developed by the two institutions achieved a certified conversion efficiency of 27.35%, surpassing the previous world record of 26.3% held by a South Korean team as recently reported by the U.S. National Renewable Energy Laboratory (NREL).
