Y 1.86 Eu 0.14 WO 6 phosphors were prepared using a solid-state reaction method. Their optical properties were analysed, and they was mixed with TiO 2 , 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 TiO 2 :Y 1.86 Eu 0.14 WO 6 (100:2.5) was 25.8% higher than that of a DSCC using pure TiO 2 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.

Sensitized Solar Cells

Directions to high efficiency dye-sensitized solar cells (DSCs) are reviewed in terms of light harvesting and charge collection. Three dimensional DSCs characterized by a double dye layer electrode, a floating electrode, and a fiber type electrode are proposed. The potentiality of each structure was discussed by using each model cell. Transparent conductive layerless electrodes were the key structures in these cells. Fabrication processes and fundamental performances are reported. Finally, it is concluded that dyes having high photoconversion efficiency in the near IR and IR regions are essential for realizing these tandem and hybrid cells.
