  • Publication number: 20130247978
    Abstract: It is disclosed that a photo-electrode of a dye-sensitized solar cell comprising faceted anatase-type titania nanoparticles which adequate for fabricating a photo-electrode of a dye-sensitized solar cell which is efficient and longlasting and a fabrication method thereof. The titania nanoparticles can provide high photoelectric conversion efficiency of the solar cell with help of fast electron mobility due to its high crystallinity and can reduce process time required for adsorbing the dye molecules on the surface of the titania nanoparticles. By modifying surface characteristics of the titania nanoparticles, it is allowed for dye molecules to be easily adsorbed on the surface of the titania nanoparticles and the life span of the dye molecules adsorbed on it is expanded with help of reduced photo-degradation rate of them at service conditions.
