The amount of the phosphor particles is 30-70 parts by weight based on 100 parts by weight of the gel type electrolyte. The average particle diameter of the metal oxide particles is 10 nm to 400 nm. The metal oxide particles comprise at least one compound selected from TiO2, WO3, ZnO, Nb2O5, SnO2, SiO2 and TiSrO3. The weight ratio of the phosphor particles to the metal oxide particles is 9:1 to 1:1. The redox couple is an iodine-based redox couple (I3-/I-). EXAMPLE - Butylmethylimidazolium iodide and iodine were dissolved in 3-methoxypropionitrile (MPN), which was a less-volatile solvent, to prepare a liquid electrolyte. The resultant liquid electrolyte was mixed with BaMgAl10O12:Eu2+ and P-25 (RTM: metal oxide particles of TiO2 having particle diameter of 20 to 25 nm) in a weight ratio of 5:5 and then stirred together to prepare a 10 wt.% suspension. The obtained suspension was milled to uniformly disperse the solid particles. Then, the resultant suspension was centrifuged at 2000 rpm for 10 minutes. The resultant was separated from the liquid phase to obtain a gel type electrolyte (test). A control liquid electrolyte was prepared by dissolving butylmethylimidazolium iodide (0.8M) and iodine (0.1M) in 3-methoxypropionitirile (MPN), which was a less-volatile solvent. The test/control electrolyte was then used in the preparation of dye-sensitized solar cell. The test/control electrolyte was evaluated for shortcut current (J-sc), open voltage (V-oc), fill factor (FF) and photoelectric conversion efficiency (Eff). The results for test/control were: shortcut current (J-sc) = 14.6/10.18, open voltage (V-oc) = 0.722/0.732, fill factor (FF) = 65.1/72.5 and photoelectric conversion efficiency (Eff) (%) = 6.86/5.40. The solar cell containing test electrolyte showed higher photoelectricity currents and better photoelectricity characteristics as compared to solar cell containing control electrolyte.
