Metal-organic frameworks at interfaces of hybrid perovskite solar cells for enhanced photovoltaic properties

In this study, metal-organic frameworks, as an interfacial layer, were introduced into perovskite solar cells (PSCs) for the first time. An interface modified with the metal-organic framework ZIF-8 efficiently enhanced perovskite crystallinity and grain sizes, and the photovoltaic performance of the PSCs was significantly improved, resulting in a maximum PCE of 16.99%. A ZIF-8 modified interface increases the grain size of perovskite crystals, resulting in a maximum PCE of 16.99%.
