Abstract

-doped TiO

(TiO

:Sm

)nanocrystals were synthesized by the sol-hydrothermal method and the down-conversion positive glow were prepared with the matrix of P25 doped with different mass fraction of the as-prepared TiO

:Sm

powder

which was used to assemble the dye-sensitized solar cell (DSSC) to improve the photoelectric properties. The fluorescence spectroscopy indicates that the TiO

:Sm

possess down-conversion feature of converting ultraviolet light to 570－700 nm visible light. When the doped content of the as-prepared TiO

:Sm

powder in the photo anode was 80%

the short circuit current density reached to 13.12 mA/cm

increased by 26.5% compared with the pure P25 photo anode

and the efficiency was also increased by 23.5%.
