NOVELTY - A laminated optical anode membrane is produced by directly preparing compact titanium dioxide (TiO2) layer on conductive surface of optical anode substrate to a thickness of 10-100 nm by magnetron sputtering and sol-gel spin coating, and preparing porous TiO2 layer on compact membrane. The porous TiO2 layer is made by preparing an oily paste from synthetic TiO2 granular material or from purchased P25 powder, through hydrothermal method; and coating or screen printing. The TiO2 granular material is formed on surface of porous TiO2 layer by liquid phase chemical deposition.    USE - Production of laminated optical anode membrane for dye-sensitized solar cell (claimed).    ADVANTAGE - The solar cell using the anode membrane has higher photoelectric conversion efficiency and longer life.    DETAILED DESCRIPTION - Production of laminated optical anode membrane comprises directly preparing compact TiO2 layer on conductive surface of optical anode substrate to a thickness of 10-100 nm by magnetron sputtering and sol-gel spin coating, and preparing porous TiO2 layer on compact membrane. The porous TiO2 layer is made by preparing an oily paste from synthetic TiO2 granular material or from purchased P25 powder, through hydrothermal method; and coating or screen printing. The TiO2 granular material, having small particle diameter of less than 8 nm, is formed on surface of porous TiO2 layer by liquid phase chemical deposition comprising:    (A) preparing 1.5-2.5 mol/L aqueous solution of titanium tetrafluoride (TiCl4) using purified water in ice water bath at 0 degrees C, storing the solution in a cold storage, and diluting the solution into 0.05-0.2 mol/L during every use;    (B) dipping laminated optical anode membrane in diluted TiCl4 solution, maintaining at 70 degrees C for 0.5-1 hour or at room temperature for 2-4 hours, and washing with deionized water and ethyl alcohol for several times to remove residual liquid on the surface; and    (C) placing laminated optical anode membrane in a resistance furnace, sintering at 450-550 degrees C for 15-30 minutes in the presence of air, and naturally cooling to form nano TiO2 granular crystal having small particle diameter on surface of nanocrystalline porous TiO2 layer having large particle diameter.
