<P>PROBLEM TO BE SOLVED: To provide an electrode substrate with high corrosion protection effect of a metal wiring layer electrically connected to a transparent conductive membrane, a photoelectric conversion element and a dye-sensitized solar battery. <P>SOLUTION: The dye-sensitized solar battery 22 includes an electrode substrate 10 equipped with a transparent substrate 12, a transparent conductive membrane 14, a metal wiring layer 16, a shielding layer 18, and a corrosion-resistant metal layer 20. A conductive substrate is provided to face the corrosion-resistant metal layer 20, and a porous semiconductor layer 28 with dye absorbed and an electrolyte 30 are provided between the transparent conductive membrane 14 and the conductive substrate. The shielding layer 18 is a deposition layer formed with metal having large corrosion resistance such as titanium or tungsten by sputtering. The corrosion-resistant metal layer 20 is a more precise layer than the shielding layer 18. For example, it is a deposition layer of which corrosion-resistant metallic vapor is changed into a plasma excitation state with the use of arc plasma, and vapor-deposited on a surface of the metal wiring layer. <P>COPYRIGHT: (C)2009,JPO&INPIT |
