NOVELTY - The multi-layer film electrode structure (2) useful in solar cell, comprises a conductive substrate (20), a titania barrier film (21) formed on the substrate for enhancing the light-power conversion efficiency of a cell, a porous titania film (22) formed on the titania barrier film for facilitating electron conductance and dye distribution, and a hybrid titania film (23) formed on the porous titania film for increasing the thickness of the whole electrode structure and increasing the amount of the absorbed dye. The hybrid titania film functions as a reflective layer.    USE - The multi-layer film electrode structure is useful in a solar cell.    ADVANTAGE - The multi-layer film electrode structure exhibits excellent adhesion to the substrate while increasing its sensitivity to sun light thus increasing the light-power conversion efficiency of the solar cell and preventing it from circuit shorting.
