Uniform perovskite films are achieved by HCl‐assisted one‐step spin‐coating at room temperature. By this method, a highest power conversion efficiency of 17.9% is obtained for perovskite solar cells (PSCs). The devices retain ≈95% of their original efficiency after storage in air for two months. The highest efficiency obtained for large‐area PSCs (0.86 cm 2 ) is 15.7%.
