The Preparation of TiO2/Eu3+,Y3+ Down-conversion Film and Its Application in Dye-sensitized Solar Cells
TiO2/Eu3+,Y3+ down-conversion film was prepared by Sol-Gel method and applicated in dye-sensitized solar cells. Ultraviolet light converted to visible light by down-conversion feature to improve the visible light intensity of dye-sensitized solar cells. TiO2/Eu3+,Y3+ powder were characterized by the X-ray diffraction and fluorescence spectroscopy, the TiO2/Eu3+,Y3+ down-conversion film were tested by the fluorescence spectroscopy and ultraviolet-visible spectrophotometer. Exposed to 396 nm ultraviolet light, down-conversion film could emit 535~620 nm wavelength visible light which showed a down-conversion features of the film. Bilayer down-conversion film still kept a higher visible light transmittance compared with a single phase TiO2 film. When total rare earth content is 4%, short circuit current is increased by 21.5% and photoelectric conversion efficiency by 14.1% with down-conversion feature of TiO2/Eu3+,Y3+ film.
