NOVELTY - The dye-sensitized solar cell comprises a first substrate (110) and a second substrate (120) separately placed so that the top surface faces, a photoelectrode including dye absorbed in an optical catalyst (115) formed on the first substrate, a counter electrode including metallic catalyst (125) formed on the second substrate, an electrolyte inlet port formed in the first substrate or the second substrate, and an electrolyte (130) injected through the inlet port and filled between the photoelectrode of the first electrode and counter electrode of the second electrode.    USE - Used as a dye-sensitized solar cell.    ADVANTAGE - The dye-sensitized solar cell has excellent sealability and durability and increased water resistance and chemical resistance.    DETAILED DESCRIPTION - The dye-sensitized solar cell comprises a first substrate (110) and a second substrate (120) separately placed so that the top surface faces, a photoelectrode including dye absorbed in an optical catalyst (115) formed on the first substrate, a counter electrode including metallic catalyst (125) formed on the second substrate, an electrolyte inlet port formed in the first substrate or the second substrate, and an electrolyte (130) injected through the inlet port and filled between the photoelectrode of the first electrode and counter electrode of the second electrode. The electrolyte inlet port includes glass frit (65-75 wt.%), binder (1-2 wt.%), plasticizer (1.5-2.5 wt.%) and solvent after injecting electrolyte, has a viscosity of 40000-80000 cPs in 30 revolution per minutes (rpm) and a composition having a viscosity rate of 1.3-1.6 in 10 rpm for viscosity in 50 rpm. The glass frit includes (in mole%): vanadium pentoxide (35-75); phosphorus pentoxide (15-30); composite acid (0-35); barium oxide ( less than or equal to 30); zinc oxide ( less than or equal to 25); arsenic oxide and antimony oxide ( less than or equal to 20); iron oxide ( less than or equal to 15); bismuth oxide, barium oxide, titanium oxide and aluminum oxide ( less than or equal to 5); and magnesium oxide (7.5). The solar cell further includes a protection layer formed in a metallic catalyst surface of the counter electrode. The glass frit has a glass transition temperature of 280-360 degrees C, curing temperature of 300-380 degrees C and firing temperature of 400-450 degrees C.
