In article number 1903369, Yoon‐Bong Hahn and co‐workers present highly stable perovskite solar cells fabricated with perovskite/Ag‐graphene and SrTiO₃/Al₂O₃‐graphene composites, achieving remarkably high photocurrent density of 25.75 mA cm⁻² and power conversion efficiency of 20.6%. This composites‐based device exhibits not only remarkable thermal‐ and photo‐stability but also long‐term stability, retaining 97–99% of the initial values of photovoltaic parameters, sustaining ≈93% of initial efficiency after 300 days under ambient conditions.
