Surface passivation is evident to be one of the most efficient approaches achieve high efficiency with superior stability perovskite solar cells (PeSCs). However, previous surface involve adding an additional coating process either before or after film fabrication, thereby introducing extra processing step and significantly increasing production costs. Here, a simple yet novel one-step interfacial approach was implemented by utilizing self-aligning properties fluorinated organic ligands (F4TmI) within precursor solution. The inherent propensity ligand spontaneously anchor onto guides crystallization perovskites, thus largely enhancing device performance humidity stability. optimized F4TmI-based devices achieved 21.1%, surpassing that control (19.8%). Moreover, improved incorporation F4TmI, maintaining 78.9 95.1% its initial aging at 60 °C 60% relative humidity, respectively, for 330 h.
