Abstract: The present invention discloses a multi-layer film electrode structure and a method preparing the same, the multi-layer film electrode comprises a substrate and three layers titania film formed from three kinds titania slurry having different properties; respectively, in which the first layer film is formed from fine titania slurry obtained by subjecting titanium alkoxide to a sol-gel reaction in an alcohol solvent, the second layer film is formed from a porous nanometer titania slurry obtained by subjecting titanium alkoxide to acidic hydrolysis in an alcohol solvent, and the third layer film is formed from a hybrid titania mixture slurry obtained by mixing the porous nanometer titania slurry with commercial available titania and metal oxide powder. The multi-layer film electrode structure of the present invention can enhance the adhesion between the titania film and the substrate and increase a light-power conversion efficiency of sensitive solar cell when it applies in solar cell field.
