Title: Large grained perovskite solar cells derived from single-crystal perovskite powders with enhanced ambient stability

In this study, we demonstrate the large grained perovskite solar cells prepared from precursor solution comprising single-crystal perovskite powders for the first time. Here, the resultant large grained perovskite thin film possesses negligible physical (structural) gap between each large grain and are highly crystalline as evidenced by its fan-shaped birefringence observed under polarized light, which is very different to the thin film prepared from the typical precursor route (MAI + PbI 2).
