Enhanced Efficiency and Stability of Tin Halide Perovskite Solar Cells Through MOF Integration.

ABSTRACT: 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 and rapid degradation in ambient conditions severely limit their stability and practical applications. This study demonstrates that incorporating UiO-66, a zirconium-based MOF, significantly enhances the performance and stability of tin halide perovskite solar cells (TPSCs). The unique porous structure and abundant carboxylate groups of UiO-66 improve the crystallinity and film quality of FASnI₃, reduce defect density, and prolong charge carrier lifetimes. Consequently, the power conversion efficiency (PCE) of UiO-66-integrated TPSCs increases from 11.43% to 12.64%, and the devices maintain over 90% of their initial
