High efficiency and air stable doctor‐blade coated perovskite solar cells are reported . The high quality mixed cation perovskite film (FA x MA 1− x PbI 3 ) is fabricated by taking the unique advantage of doctor‐blade coating method, based on which solar cell efficiency larger than 18% is realized. In addition, choosing copper as cathode enhances device environmental stability substantially, paving the way for real applications.
