The dye- and titania gel-modified multiwalled carbon nanotube nanoelectrodes were prepared by sol-gel at room temperature. The photoelectric conversion properties of the nanoelectrodes were examined by simple spectroscopic and electric measurements. The photocurrent spectrum originated from the absorption of the dye. The open-circuit voltage was due to the semiconducting characteristics of the titania gel. The experimental results indicated electron transport from the dye excited states to the carbon nanotubes through the titania gel.
