Abstract

Perovskite Solar Cells In article number 2302418, Hyungjun Kim, Ki-Ha Hong, Sang Hyuk Im, Chang Eun Song, and co-workers demonstrate a defect-passivation strategy using L-asparagine, which can effectively suppress tin oxidation. L-asparagine as a zwitterion revolutionizes film morphology and energy-level matching, boosting power conversion efficiency to a remarkable 13.31%. Surpassing limitations are tied to tin halide perovskite instability. This work offers transformative insights and practical strategies for advancing tin-based perovskite electronic devices.
