Methylammonium chloride (MACl) in perovskite solar cells (PSCs) is a key additive known to enhance film quality dimethyl sulfoxide (DMSO)-based systems, where an optimal concentration of 50 mol% typically required. However, alternative solvent such as N-methyl-2-pyrrolidone (NMP), have shown potential reduce concentrations while maintaining high performance. This study explored the NMP/DMF (1:9) system and its impact on MACl optimization. The NMP-based systems was reduced 20–30 mol%, representing substantial decrease from required DMSO-based formulations. Films produced under these conditions exhibited superior crystallinity, evidenced by narrower full-width at half maximum (FWHM) values X-ray diffraction (XRD), defect densities. These structural improvements translated into enhanced optoelectronic properties, with devices achieving efficiency exceeding 23%, compared ~20% for counterparts. Furthermore, demonstrated improved long-term stability continuous illumination.

Abstract This study utilizes a method to enhance the structural and thermal stability of perovskite solar cells (PSCs) by incorporating an alkali halide interlayer between electron transport layer (ETL) perovskite, which is known improve device efficiency. passivation technique significantly reduces residual stress within at room temperature (3.68 MPa → 2.56 MPa) maintains integrity under cycling (−40 85 °C) as per IEC 61215: 2016 standards. Following 50 cycles, treated film exhibits minimal increase in (≈5.34 MPa), contrast control (≈29.72 based on Williamson‐Hall 2θ – Sin 2 Ψ analysis. The incorporation wide‐bandgap halides facilitates strong lattice registry, thereby enhancing reliability. Moreover, fluorescence lifetime imaging microscopy (FLIM) confirms reduction defect formation, correlating with macroscopic studies. also increases open circuit voltage ( V OC ) (1.08 1.15 V) efficiency (17.9% 20.6%). Notably, retains ≈71% its initial PCE after whereas devices ceased operation 30 cycles due stress‐induced interfacial delamination. approach effectively prevents delamination, improving long‐term reliability and, thereby, enabling efficient thermally stable PSC deployment.
