In this study, we report a facile method to sequentially electrodeposit a TiO2 compact layer and a mesoporous scaffold from a single solution. This bilayer TiO2 structure offers good controllability on the thickness and morphology by simply adjusting the depositing parameters. Currently, perovskite solar cell containing an electrodeposited TiO2 bilayer exhibits similar power conversion efficiency when compared with the one using double spin-coating techniques, showing great potential to replace conventional tedious TiO2 film fabrication.
