In article number 1903239, Junsheng Yu, Wei Huang, Ziyi Ge, Tobin J. Marks, Antonio Facchetti, and co‐workers present a spontaneous passivation method to greatly improve the performance of perovskite solar cells (PSCs) by using a zwitterionic small‐molecule electrolyte. This bottom‐up passivation is a novel and promising strategy to overcome outstanding issues impeding PSC advances in the future.
