Surface passivation engineering strategy to fully-inorganic cubic CsPbI3 perovskites for high-performance solar cells
Abstract
Inorganic cesium lead iodide perovskite is inherently more stable than the hybrid perovskites but it undergoes phase transition that degrades the solar cell performance. Here Li et al. stabilize it with poly-vinylpyrrolidone and obtain high efficiency of 10.74% with excellent thermal and moisture stability.
