In article number 1900245 , Jae‐Joon Lee, Ashraful Islam, and co‐workers introduce a post‐deposition vapor annealing process, assisted by methylammonium chloride vapor to fabricate stable, homogeneous pin‐hole‐free FASnI 3 perovskite absorber films with low crystal defects and low surface recombination over a relatively large area. Inverted planar Pb‐free perovskite solar cells fabricated with a 1.02 cm 2 aperture area show a maximum power conversion efficiency of 6.33% with high reproducibility and stability.
