The addition of Sr 2+ in CH 3 NH 3 PbI 3 perovskite films enhances the charge carrier collection efficiency of solar cells leading to very high fill factors, up to 85%. The charge carrier lifetime of Sr 2+ ‐containing perovskites is in excess of 40 μs, longer than those reported for perovskite single crystals.
