<P>PROBLEM TO BE SOLVED: To provide a dye-sensitized solar cell in which charge recombination speed on the oxide semiconductor surface of the solar cell is decreased and efficiency is improved. <P>SOLUTION: The oxide semiconductor membrane of the dye-sensitized oxide semiconductor electrode which is equipped with a conductive substrate, an oxide semi-conductor membrane provided on the surface of the conductive substrate, and a sensitized-dye adsorbed on the oxide semiconductor membrane is further treated and passivated by a silanizing agent of one kind or more containing a partial structure R<SP>1</SP>-Si-OR<SP>2</SP>(wherein, R<SP>1</SP>and R<SP>2</SP>are each independently alkyl group or R<SP>1</SP>is alkyl group and R<SP>2</SP>is hydrogen or aryl group). The solar cell equipped with the electrode that is passivated by this treatment shows an improved efficiency and other useful characteristics compared with a similar electrode that does not have the passivated electrode. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
