Abstract

Double layer coating on TiO₂ surfaces was performed to improve the performance of dye-sensitized solar cells (DSSCs). Nanoporous TiO ₂ electrode was first treated with TiCl₄ followed by sintering, and then a dilute aqueous solution of Li₂ CO₃ was applied to doubly modify TiO₂ surface via a dip coating process. The DSSC with the doubly modified TiO₂ film showed a power conversion efficiency of 9.85%, enhanced from that (8.70%) of pristine TiO₂ -based device, due to an improvement in short circuit current and open circuit voltage.
