NOVELTY - A transparent conductor film (22) comprises mesh-shaped electroconductive film (23) which consists of metal or alloy and coating membrane (24) which is formed on electroconductive film and contains organosilicon compound and conductive polymer.    USE - A transparent conductor film for transparent electrode used for dye-sensitized solar cell (all claimed).    ADVANTAGE - The film provides the electrode with corrosion resistance to iodine ion contained in electrolyte solution used for dye-sensitized solar cell, low resistance value, excellent durability with respect to electrolyte solution, and excellent transparency. Internal resistance of transparent electrode can be suppressed which reduces loss of photoelectric efficiency, and highly efficient dye-sensitized solar cell can be obtained.    DETAILED DESCRIPTION - A transparent conductor film comprises mesh-shaped electroconductive film which consists of metal or alloy and coating membrane which is formed on electroconductive film and contains organosilicon compound of formula SiOx(OH)yR4-x-y (1) and conductive polymer.    R=organic functional group;    x=0-2;    y=0-4; and    (2x+y)=0-4.    INDEPENDENT CLAIMS are included for:    (1) transparent electrode (11) comprising transparent conductor film formed on transparent base material (21); and    (2) manufacture of transparent conductor film which involves hydrolyzing liquid mixture containing silicon alkoxide and/or organic modified silicon alkoxide to obtain hydrolyzed product of alkoxide, adding and mixing conductive polymer in dispersion liquid containing the hydrolyzed product of alkoxide to produce coating material for coating membrane formation, forming coating film on mesh-shaped electroconductive film which consists of metal or alloy using the coating material for coating membrane formation, and drying and curing coating film to form coating membrane on electroconductive film.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional diagram of the transparent electrode of a dye-sensitized solar cell.
