Using a two-step deposition technique to prepare perovskite (CH3NH3PbI3) for thin film solar cells based on ZrO2 and TiO2 mesostructures

Michael Graetzel, Mohammad Khaja Nazeeruddin, Ulf Anders Hagfeldt, Soo-Jin Moon, Lin Yang, Dongqin Bi

A two-step deposition technique is used for preparing CH3NH3PbI3 perovskite solar cells. Using ZrO2 and TiO2 as a mesoporous layer, we obtain an efficiency of 10.8% and 9.5%, respectively, under 1000 W m(-2) illumination. The ZrO2 based solar cell shows hi ...
