New US Perovskite Solar Panel with Highest Efficiency in 2025

New US Perovskite Solar Panel with Highest Efficiency US scientists have created a 108 centimeter square perovskite solar module boasting 19.21% efficiency. They treated the perovskite solar cells with trifluoromethane sulfonate to counteract iodide defects. This achievement, confirmed by the US National Renewable Energy Laboratory (NREL), marks the highest efficiency for its size to date. Researchers led by the University of North Carolina at Chapel Hill developed new mini solar modules using perovskite cells treated with zinc additives. These additives, incorporated into perovskite ink at a minute percentage, enhance reproducibility in fabrication, thereby reducing costs. The team identified that nonuniformity in perovskite films stems from oxidized perovskite inks, particularly the oxidation of iodide to molecular iodine during the fabrication process in ambient environments. By introducing zinc additives into perovskite ink, the researchers observed improved device efficiency due to defect passivation, leading to enhanced open-circuit voltage and fill factor. Utilizing optimized concentrations of zinc additives, the researchers blade-coated perovskite films ranging from 78 cm2 to 108 cm2, each comprising 20 sub-cells with a width of 6.5 mm. These mini modules achieved power conversion efficiencies of 19.60% and 19.21% for aperture areas of 84 cm2 and 108 cm2, respectively, certified by the National Renewable Energy Laboratory. Furthermore, the incorporation of zinc additives mitigates iodine generation during perovskite solution or device aging, while also reducing iodide interstitial concentration throughout the films, resulting in enhanced device efficiency and stability. These findings, published in Nature Communications, hold promise for commercialization, contingent upon application to equipment capable of handling larger-size modules, such as slot-die coaters or roll-to-roll coaters.
