▎ 摘　　要

NOVELTY - A perovskite film positioning and growing method involves utilizing graphene-assisted method, transferring a layer of graphene grown by chemical vapor deposition on the target substrate, spin-coating a photoresist and positioning a target region on the graphene to grow a perovskite film by UV exposure lithography. The target substrate is bombarded with oxygen plasma, followed by removing graphene in the target region, hydrophilizing the target region, removing the photoresist, spin coating the perovskite precursor solution and annealing to grow a perovskite film in the target region, removing the residual graphene and achieving the localized growth of the perovskite film. USE - Method for positioning and growing perovskite film. ADVANTAGE - The method enables realizing locating and growing the perovskite film on any substrate, with reduced requirement of hydrophobic substrate.
