Method for preparing quantum dot sensitized titanium oxide nanotube photoelectrochemical cell

The invention relates to a method for preparing a quantum dot sensitized titanium oxide nanotube photoelectrochemical cell by taking a titanium foil as a substrate conductive material, belonging to the technical field of solar cell production. The method comprises the steps of: cutting a titanium foil substrate and polishing the titanium foil substrate by using an anodization eroding method, thereby obtaining a bright titanium foil substrate; preparing a titanium oxide nanotube array by using an anodization method, and cleaning after the anodization is completed; drying; and assembling CdS and CdSe quantum dots and combination thereof on the titanium oxide nanotube array by using a chemical bath method. In addition, a cathode is selected to compose two electrode systems so as to assemble to form the photoelectrochemical cell. According to the method for preparing the quantum dot sensitized titanium oxide nanotube photoelectrochemical cell, the anodization method which is low in cost, environment-friendly and convenient and simple to operate is adopted, therefore, titanium oxide nanotube array films with required area and quantity and regular appearance can be rapidly prepared, andindustrial production can be realized; and the prepared quantum dot sensitized titanium oxide nanotube photoelectrochemical cell has superior performance and high photoelectric conversion efficiency.
