ABSTRACT Organometallic halide perovskites have received significant attention due to their promising optoelectronic properties, particularly in photovoltaics. The formation process of perovskite films is crucial determining structural and functional characteristics. In this study, the effects methylamine vapour treatment vacuum annealing on enhancing crystallinity, morphology integrity are examined. Methylammonium lead iodide (MAPI)–based investigated, with a focus crystallographic structure, vibrational modes correlation device performance. Power conversion efficiencies (PCEs) 19.5% 18.6% been achieved using one‐step two‐step processes, respectively. influence trap states, film homogeneity interfacial properties has analysed through capacitance, photoluminescence electroluminescence measurements, recombination behaviour linked properties. These findings provide valuable insights into role processing techniques rejuvenation solar cells. Additionally, they offer guidance for optimising fabrication strategies improve quality, performance, stability long‐term reliability.
