Tin halide perovskites are promising candidates for lead-free perovskite solar cells due to their ideal bandgap and high charge-carrier mobility. However, poor crystal quality rapid degradation in ambient conditions severely limit stability practical applications. This study demonstrates that incorporating UiO-66, a zirconium-based MOF, significantly enhances the performance of tin (TPSCs). The unique porous structure abundant carboxylate groups UiO-66 improve crystallinity film FASnI₃, reduce defect density, prolong charge carrier lifetimes. Consequently, power conversion efficiency (PCE) UiO-66-integrated TPSCs increases from 11.43% 12.64%, devices maintain over 90% initial PCE after 100 days nitrogen glovebox. These findings highlight potential addressing challenges perovskites.

Methylammonium chloride (MACl), a common additive, is used control the crystallization of FAPbI3, thereby facilitating formation photoactive α-phase. However, MACl's high volatility raises concerns regarding its stability and potential impact on device.

The FAPbI3 film containing PACl demonstrates enhanced photoluminescence intensity lifetime. Additionally, PACl's presence at grain boundaries acts as protective layer for PSCs. Consequently, achieved power conversion efficiency (PCE) 22.4% exceptional stability.
