The dye-sensitized solar cell (DSC) is a promising alternative to the inorganic solar cell. We have constructed a solar cell in the configuration ITO glass/Ru-red dye-absorbed TiO₂ nano-powder/iodine electrolyte/ sputtered Pt/ITO glass, and have used a Eu-doped LiGdF₄(LGF) luminescent material for high-energy-photon dividing. The excitation spectrum maximum of LGF appeared at around 275 ㎚, and emission spectrum maxima appeared at around 590 and 610 ㎚. The mean particle size of the TiO₂powder was about 70 ㎚ and, thus, the solar absorption dye can be absorbed sufficiently to that surface. The short circuit photocurrent density and the conversion efficiency of the cell at an excitation wavelength of 600 ㎚ were 1.075 ㎃/㎠ and 4.8%, respectively; the fill fact of the dye-sensitized solar cell was 0.42. The results seem to be related to the incidentphoton-to-current conversion efficiency (1PCE) of N3, which is 60 80% in the wavelength range from 350 to 650 ㎚, but rapidly drops upon increasing the wavelength and reaches zero at wavelengths > 800 ㎚. After correcting for the losses due to light reflection and absorption by the conducting glass, the conversion of photons to electric current is practically quantitative in the plateau region of the curves. The IPCE of N3 used as a dye in this work is about 80% at around 590 and 610 ㎚, which corresponds to the emission spectrum of Eu-doped LGF.
