NOVELTY - Optical anode of dye-sensitized solar cell comprises a mixed scattering layer (2) in close contact with a transparent conductive glass (1) and an absorbing layer (3) in contact with the mixed scattering layer. The mixed scattering layer consists of large-particle titanium dioxide fine grains and small-particle titanium dioxide fine grains mixed with each other, and the thickness of the mixed scattering layer is 4-6 mu m and the absorbing layer consists of small-particle titanium dioxide fine grains, and the thickness of the absorbing layer is 10-12 mu m.    USE - Used as an optical anode of dye-sensitized solar cell.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the optical anode of dye-sensitized solar cell, comprising: (i) mixing small-particle titanium dioxide powder and ethyl cellulose and adding terpinol and absolute ethyl alcohol, stirring to prepare the absorbing layer slurry; (ii) mixing the large-particle titanium dioxide powder and the small-particle titanium dioxide powder, and then mixing the mixed powder and the ethyl cellulose, and adding terpinol and absolute ethyl alcohol, stirring to prepare the mixed scattering layer slurry; (iii) carrying out screen printing to the mixed scattering layer slurry prepared in the step (ii) on the transparent conductive glass after being treated, allowing it to stand for 3-5 minutes after each printing and drying and printing again and again so that the thickness of the mixed scattering layer film is 4-6 mu m; (iv) carrying out screen printing to the absorbing layer slurry prepared in the step (i) on the mixed scattering layer prepared in the step (iii), allowing it to stand for 3-5 minutes after each printing and drying, where the drying temperature is 110-130 degrees C and printing again and again so that the thickness of the absorbing layer film is 10-12 mu m; (v) placing the transparent conductive glass printed with the mixed scattering layer and the absorbing layer after passing the step (iii) and the step (iv) into an atmosphere furnace and leading in oxygen to carry out single atmosphere sintering, where the sintering time is 15-45 minutes to obtain the optical anode of dye-sensitized solar cell.
