Abstract

Humidity can accelerate degradation by promoting phase transitions and enhancing the defect generation in perovskites. This poses a significant challenge for the upscaling of perovskite solar modules under ambient conditions, especially for moisture-sensitive inorganic CsPbI₃ perovskite. Herein, we report an environmental moisture-induced chemical passivation of the CsPbI₃ perovskite surface by the hydrolysis of perfluorobutanesulfonyl chloride (PFSC). The in situ generated perfluorobutanesulfonic acid (PFS) effectively reduces defect density and improves the interfacial contact, leading to CsPbI₃-based devices with suppressed non-radiative recombination losses. Our in situ surface-modified PFS-CsPbI₃ perovskite solar modules with an aperture area of 12.82 cm² deliver a state-of-the-art certified aperture area efficiency of 18.22%.
