Preparation of CH3NH3PbI3 thin films with tens of micrometer scale at high temperature

Abstract The fabrication of high-quality organic-inorganic hybrid halide perovskite layers is the key prerequisite for the realization of high efficient photon energy harvest and electric energy conversion in their related solar cells. In this article, we report a novel fabrication technique of CH3N...
