A novel sequential layer‐by‐layer sub‐100 °C vacuum‐sublimation method to fabricate planar‐type organometal halide perovskite solar cells is developed. Very uniform and highly crystalline perovskite thin films with 100% surface coverage are produced. The cells attain maximum and average efficiencies up to 15.4% and 14%, respectively. This low‐ temperature, all‐vacuum process is suitable for a wide variety of rigid and flexible applications.
