染料敏化太阳能电池Sm3+掺杂TiO2下转换光阳极的制备及性能
Synthesis and Properties of Sm3+-doped TiO2 Down-conversion Photoanode for Dye-sensitized Solar Cells
摘要
Abstract
Sm3+-doped TiO2 ( TiO2∶ Sm3+) nanocrystals were synthesized by the sol-hydrothermal method and the down-conversion positive glow were prepared with the matrix of P25 doped with dif-ferent mass fraction of the as-prepared TiO2∶Sm3+ powder, which was used to assemble the dye-sen-sitized solar cell ( DSSC) to improve the photoelectric properties. The fluorescence spectroscopy in-dicates that the TiO2∶Sm3+ possess down-conversion feature of converting ultraviolet light to 570-700 nm visible light. When the doped content of the as-prepared TiO2∶Sm3+ powder in the photo anode was 80%, the short circuit current density reached to 13. 12 mA/cm2 , increased by 26. 5%compared with the pure P25 photo anode, and the efficiency was also increased by 23. 5%.关键词
