In this work, optical properties of perovskite solar cells (PSCs) with planar and nanorod-based SnO2electron transport layers (ETLs) are studied and their photovoltaic parameters are compared using computer simulation methods. It is found that nanorod-based SnO2 ETLs improve the light harvesting ability of device. However, their power conversion efficiencies (PCEs) are still lower than those with thin planar SnO2ETLs.
