Abstract

Different lengths of rutile TiO₂ nanowires (NW) with wide-open space for effective material filling were used as photoanodes for perovskite solar cells. Cells with 900 nm nanowires as photoanodes exhibit a current density of 22 mA cm⁻² and an efficiency of 11.7%, outperforming the reported TiO₂ nanowire-based perovskite solar cells.
