Abstract Up to now, post‐annealing is most commonly used post treat the perovskite film accelerate ripening process. Nonetheless, top‐down crystallization mechanism impedes efficient desolvation of solvent complexes. Thus, residual complexes tend accumulate at bottom during process and deteriorate device. Here, a new strategy with unique concept promoted amplify film, in which nematic thermotropic liquid crystal (LC) molecular introduced facilitate conversion by utilizing crystalline behavior under external field. Upon concurrent application thermal force fields, covalent interaction between LC generates driving force, promotes upward migration complexes, thereby facilitating their engagement In addition, fields assists flattening grain boundary grooves. Therefore, quality improved efficiently amplified adequately handled buried interface. Based on positive effects, devices achieve champion efficiency 25.24%, sustained ≈75% its initial level even after undergoing damp heat test (85 °C/85% RH) for 1400 h.
