In article number 201901235, Olga S. Ovchinnikova and co‐workers report a coupled strain and chemical gradient in methylammonium lead iodide (CH 3 NH 3 PbI 3 ) perovskite. The proposed mechanism concerning how the strain–chemical gradient affects the properties of CH 3 NH 3 PbI 3 provides novel insights into the effect of strain and ion migration on the optoelectronic performance of this perovskite material.
