Abstract

A low-temperaure hydrothermal method has been used to grow ZnO nanostructures including two distinct morphologies, nanodisks and nanowells as electron-transporting materials (ETMs) for high-efficieny perovskite solar cells. The perovskite solar cells based on ZnO nanowells demonstrate the maximum power conversion efficiency (PCEmax) of 16.65%, compared to ZnO nanodisks and mesoporous film, possibly thanks to better morphology, faster electron transport and complete infiltration of the perovskite absorber into the ZnO nanowells.
