In article number 1801079 , Chuanjiang Qin, Chihaya Adachi, and co‐workers adopt thermally stimulated current and electrochemical impedance spectroscopy measurements to reveal that carrier traps are generated in solar cells with CH 3 NH 3 PbI 3 as a light absorber after operation at 85°C, which is higher than its phase transition temperature. Perovskite alloys‐based solar cells with improved thermal stability under a standard thermal cycling test are demonstrated.
