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 TiCl ₄-treated TiO₂ nanotubes exhibited a conversion efficiency of 1.45% and showed improved electron transfer.
