In article number 2002639, Liang Li, Hongqiang Wang, and co‐workers demonstrate a double‐barrier strategy that not only blocks the invasion of moisture but also employs the permeated moisture to increase the moisture durability of perovskite films, which results in an n–i–p perovskite solar cell with moisture stability over 115 days (relative humidity of 70%) and a champion efficiency up to 21.34%.
