Y1.86Eu0.14WO6 phosphors were prepared using a solid-state reaction
method. Their optical properties were analysed, and they was mixed with
TiO2, sintered, and used as a photoelectrode (PE) in dye-sensitized solar
cells (DSSCs). The as-prepared photoelectrode was characterized by
photoluminescence spectroscopy, diffuse reflectance, electrochemical
impedance spectroscopy (EIS) and X-ray diffraction. The photoelectric
conversion efficiency of the DSSC with TiO2:Y1.86Eu0.14WO6 (100:2.5) was
25.8% higher than that of a DSCC using pure TiO2 as PE. This high
efficiency is due to the ability of the luminescent material to convert
ultraviolet radiation from the sun to visible radiation, thus improving
the solar light harvesting of the DSSC.
