Research Abstract

The dye-titania compositionally graded electrodes consisting of multi-layers were prepared by layering the dye-containing titania gel by the sol-gel coating and controlling steam-treatment of the films. Formation of the differences between the conduction band edges of the neighboring titania layers promoted the electron injection and transport process in the multi-layers. The performance of the working electrodes was improved by the control of the conduction band level.
