Abstract

TiO2 nanotube arrays were grown on Ti foil in mixed electrolyte by the anodizing process. TiO2 nanotube arrays were immersed in the TiCl4 solution to improve the photocurrent by enhanced charge transfer between TiO2 and dye molecules on the activity surface. Internal resistance of dye-sensitized solar cells (DSSC) was measured by impedance spectroscopy measurements. Backside illuminated DSSC with TiCl4-treated TiO2 nanotubes exhibited a conversion efficiency of 1.45% and showed improved electron transfer.
