Zusammenfassung:Perovskite Solar Cells In article number 2204726, Juan‐Pablo Correa‐Baena and co‐workers demonstrate the thermal instability of the bulky‐cation interface layers used in state‐of‐the‐art halide perovskite solar cells. Under thermal stress, the interface reconstructs, impacting charge‐carrier dynamics and device operation. Characterization of bulky‐cation interfaces before and after annealing to drive the selection of bulky cations toward efficient and stable devices is proposed.
