Abstract: The light harvesting efficiency of dye-sensitized photoelectrodes was enhanced, by coupling a TiO2 photonic crystal layer to a conventional film of TiO2 nanoparticles. The inverse opal photonic crystal caused a significant change in dye absorbance, which depended on the position of the stop band.
