First, spin coating CH3NH3I (MAI) and thermal evaporate PbI2. Second, evaporate MAI at low pressure by SET chamber. Through the double-interdiffusion of MAI and PbI2, we adjust the reaction conditions by different evaporation time and chlorobenzene added, which called anti-solvent vapor-assisted crystallization (AVC), can spend less time and cost to make better morphology of perovskite crystallize and enhance to high PCE=13.08%. ? 2021 IEEE.anti-solvent vapor-assisted crystallizationdouble-interdiffusionperovskitesandwich evaporation techniqueEvaporationLayered semiconductorsLead compoundsPerovskite solar cellsSolventsAnti-solvent vapor-assisted crystallizationAnti-solventsCrystallization controlDouble-interdiffusionLow pressuresPerformancePerovskite layersSandwich evaporation techniqueSolvent vaporsThermalPerovskite[SDGs]SDG7conference paper10.1109/PVSC43889.2021.95186022-s2.0-85115962512
