Abstract

The invention discloses a preparation method of a composite ordered porous nanometer titanium dioxide (TiO2) film. The method comprises the following steps: synthesizing a polystyrene microsphere emulsion and assembling a polystyrene microsphere colloidal crystal template; preparing a modified sol-gel doping precursor body; using a sol-gel dip-coating method to prepare a composite ordered porous nanometer TiO2 film. The invention provides the anatase phase composite porous TiO2 film with doping modification, an ordered structure and a high specific surface area, wherein the film is prepared by the PS colloidal crystal template and through a sol-gel process. The film can be applied in a DSSC.

Description

technical field [0001] The invention relates to dye-sensitized solar cell technology in the field of solar photoelectric utilization, in particular to a method for preparing a nanocomposite ordered porous electrode of a dye-sensitized solar cell. Background technique [0002] With the continuous development of economy and society, energy crisis and environmental pollution have become serious challenges to the survival and development of all human beings. Dye-sensitized solar cells (DSSCs) have become an important research direction due to their high photoelectric conversion efficiency, low cost, and simple process. Among them, porous titanium dioxide (TiO 2 ) nanocrystalline film-based DSSC has achieved a photoelectric conversion efficiency of 11%. [0003] The core part of the dye-sensitized solar cell is a nanocrystalline film. Porous films with a large specific surface area are commonly used at home and abroad to increase the adsorption amount of dyes and improve the abs...
