Patent ID: 8106294

Claim:
A dye-sensitized solar cell comprising: a transparent electrode substrate having a transparent conductive film; a porous oxide semiconductor electrode formed on the transparent electrode substrate; a dye adsorbed to the porous oxide semiconductor electrode; a counter electrode substrate on which a catalyst film and a transparent conductive film are formed; a sealing material sealing peripheries of the transparent electrode substrate and the counter electrode substrate; and an iodine electrolyte solution filled between the transparent electrode substrate and the counter electrode substrate, wherein the sealing material includes a glass composition, the glass composition comprising, in terms of mass %, 45 to 70% of V 2 O 5 , 10 to 50% of P 2 O 5 , and 0 to 22% of BaO, and having a mass reduction of 0.1 mg/cm 2 or less after being immersed in an iodine electrolyte solution at 25° C. for 2 weeks.
