We have successfully introduced green phosphors LaPO4:Ce, Tb (G4) or (Mg, Zn)Al11O19:Eu (G2) into TiO2 photoelectrode of dye-sensitized solar cells. The conversion efficiency of the G4-doped device was enhanced by 30% compared with the pristine TiO2 photoelectrode. The green phosphor doped at 5-wt.% ratio contributed to the reduction of resistances of the surface and interface of the photoelectrode and to the great enhancement of the absorption spectrum in UV-visible and near-infrared regions. The internal resistances and absorbance of the photoelectrode directly affect the power conversion efficiency. Green phosphor plays an important role towards the realization of high-efficiency dye-sensitized solar cells.

我们已成功地将绿色荧光粉 LaPO4:Ce、Tb(G4)或(Mg、Zn)Al11O19:Eu(G2)引入染料敏化太阳能电池的 TiO2 光电极中。与原始 TiO2 光电极相比，G4 掺杂器件的转换效率提高了 30%。以 5wt.%比例掺杂的绿色荧光粉有助于降低光电极表面和界面的电阻，并极大地增强光电极在紫外可见和近红外区域的吸收光谱。光电极的内阻和吸收率直接影响功率转换效率。绿色荧光粉在实现高效染料敏化太阳能电池方面发挥着重要作用。
