a PL mapping results for PbI2-FACsMA and amo-FACsMA films (area: 10 μm × 5 μm), respectively. b TRPL curves of PbI2-FACsMA and amo-FACsMA films. c Density of states of traps (tDOS) deduced from the room-temperature C–f plots for PbI2-FACsMA and amo-FACsMA. XRD results of perovskite films after (d) 55 °C heating, (e) 1 sun illumination, and (f) 55 °C heating + 1 sun illumination stability test in a glove box, the diamond represents PbI2.
