In article 1800361 , Byungwoo Park and co‐workers present the role of imidazole as a cation solute for organometal‐halide perovskites. Imidazole is structured with the aromatic and diamine framework, allowing significant improvements on the device performance and stability. Considering the intense attention on stability problems in perovskites, degradation under various conditions are examined to reveal the superior role of imidazole.
