Buried Interface Modification for High Performance and Stable Inverted Perovskite Solar Cells

) loss reported for comparable 1.55 eV bandgap PSCs, while maintaining excellent long-term stability. Importantly, this strategy also enabled a corresponding flexible PSC (F-PSCs) to achieve a remarkable PCE of 24.39%. Collectively, these results demonstrate a promising pathway for buried interface modification of perovskite films and the fabrication of high-performance F-PSCs.
