In article number 2100557, Nripan Mathews, Subodh Mhaisalkar, Annalisa Bruno, and co‐workers show that the perovskite growth process can substantially affect the thermal stability. Un‐encapsulated co‐evaporated MAPbI 3 solar cells demonstrate remarkable structural robustness and are able to maintain over ≈80% of their initial power conversion efficiency under 3600 h continuous thermal aging at 85 °C. This excellent stability is indeed related to the perovskite growth process, leading to compact and almost strain‐stress‐free films.
