Embodiment 1
[0045] see figure 1 , figure 1 Shown is a flow chart of the method for preparing the first titanium foil for the dye-sensitized solar cell photoanode of the present invention. The method for preparing the first titanium foil of the photoanode of the dye-sensitized solar cell comprises the following steps:
[0046] Executing step S11: cutting, polishing, and cleaning the first titanium foil; in this embodiment, preferably, the cleaning process specifically includes successively passing ultrasonic waves through detergent solution, deionized water, and ethanol solution. Clean for 5-15 minutes, and dry with clean gas;
[0047] Execute step S12: respectively configure HF / H2O mixed solution with a volume ratio of 1:6, and HNO3 / H2O mixed solution with a volume ratio of 1:3, and place the first titanium foil in the HF / H2O mixed solution in sequence. Soak in the solution and the HNO3 / H2O mixed solution for 1-5 minutes respectively. Preferably, each soaking time is 2min. Subsequent...
