The US National Renewable Energy Laboratory (NREL) has achieved remarkable efficiency and stability for a wide-bandgap all-perovskite tandem solar cell. The scientist developed the device with an inverted architecture and used gas quenching instead of an antisolvent in the manufacturing process.NREL researchers have fabricated an all-perovskite tandem solar cell with perovskite films to show reduced defect density and achieve a power conversion efficiency of 27.1%. The new cell builds on another inverted perovskite solar cell fabricated with p-i-n structure, which was unveiled by the research ...Den vollständigen Artikel lesen ...
