Preparation of TiO2/Eu3+ Down-conversion Film and Its Application in Dye-sensitized Solar Cells
down-conversion film was prepared by sol-gel method
and its optical and photoelectric properties were analyzed. Applying it to dye-sensitized solar cells (DSSC)
partial UV light can be converted to visible light and absorbed by dye according to its down-conversion feature
as thus
the visible light intensity and short circuit currents are improved. The fluorescence spectra show that the down-conversion film can emit 550-640 nm visible light under 394 nm UV light excitation
which indicates a down-conversion feature of the film. The down-conversion film can increase the wavelength range of DSSC absorption. When bilayer down-conversion films are coated on DSSC
the short circuit current increases from 8.05 mAcm
-2
to 9.62 mAcm
-2
the photoelectric conversion efficiency increases from 3.67% to 4.32%.
