Stereoelectronic Effect from B-Site Dopants Stabilizes Black Phase of CsPbI<inf>3</inf>
Phase stability remains a critical bottleneck hindering the use of CsPbI3 perovskites, which prefer to take on a non-perovskite, “yellow” phase at room temperature. The desired “black” phase perovskite, suitable for photovoltaic applications, can be obtained at elevated temperatures but readily reve...
