A novel photoelectrochemical cell consisting of a modified electrode with a self-assembled monolayer of a tris(2,2′bipyridine)ruthenium(II)-viologen linked thiol on the surfaces of a gold-particle multistructure, an indium-tin-oxide (ITO) electrode, and an aqueous electrolyte solution containing hydroxymethylferrocene, has been fabricated. The modified electrode was constructed by the precipitation of gold nanoparticles on a planar gold electrode, and by subsequent self-assembling of the thiol compound on the surfaces of the multistructure. The spatial separation between the modified electrode and the ITO electrode was as small as ∼12 μm, which was determined from the thickness of a polyimide film used for electrical insulation. The performance of the photoelectrochemical cell was investigated. Photocurrents and photovoltages increased with increasing number of immobilized molecules.
