The phase instability of cesium lead halide perovskite is still a substantial challenge hindering its application. A 2D-3D all-inorganic Cs2PbI2Cl2-CsPbI2.5Br0.5 perovskite solar cell was successfully developed to address this issue. The 2D Cs2PbI2Cl2 phase distributed among the grain boundaries of the 3D CsPbI3-xBrx grains. The existence of […] View
