Method for preparing nanocrystalline titanium dioxide film used by dye sensitization solar battery

Abstract

The invention relates to a method for preparing the nanometer Titania film of dope sensitized solar-energy battery. Wherein, it uses organic titanate as titania source, uses polymer template solvent, to be dissolved in organic solvent to prepare initial slurry, and uses silk screen print technique to print titania film at the surface of conductive glass, then treats at high temperature to obtain the nanometer titania film. The inventive product has high transmission rate, large surface area, high stability and long service life. And the invention has low cost while it can be used in optical catalyst, glass plating, and sensor.

Description

technical field

[0001] The invention relates to a new method for preparing a nanocrystalline titanium dioxide film, which belongs to the fields of new material technology and new energy technology. Background technique

[0002] Dye-sensitized solar cell is a new type of chemical solar cell developed in the 1990s. It has low cost, simple preparation process and good environmental compatibility and has a good application prospect. Preparation of high-performance titanium dioxide film is the key to improving its photoelectric conversion efficiency, and a simple preparation process is also a prerequisite for reducing its cost and moving toward practicality. However, for a long time, the preparation of titanium dioxide film has relied on hydrothermal technology, which requires high temperature and high pressure conditions and a special reactor. In addition, the preparation process is relatively complicated, and the controllability of the titanium dioxide film is not perfect. The ...
