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

Abstract

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 higher photovoltage and longer electron lifetime than the TiO₂ based solar cell.
