Method for for preparing cadmiumsulfide quantum dot sensitized porous titanium dioxide photoelectrode

Abstract

This invention discloses a method for preparing CdS quantum point sensitized porous TiO2 photo-electrode including the following steps: bathing a surface-active agent and melting it, adding n-butyl alcohol and hexamethylene alkyl to get a mixed solution, then adding Cd(NO3)2 and sulfocarbamide into the solution and adding deionized water after being dissolved to form a micro emulsion solution to be poured into a reaction kettle to be composed in hot water, then repeatedly cleaning the reaction product to be dried in vacuum and filled with alcohol to form an alcohol solution of CdS quantum points, preparing a TiO2 porous film with a sol gel method or a hot-water crystal method to be dipped in an alcohol solution of oxalic acid and acetic acid then in the CdS quantum point alcohol to assemble it on the surface and in the cavities of the TiO2 porous film.

Description

technical field

[0001] The invention relates to a method for preparing an inorganic semiconductor quantum dot sensitized porous titanium dioxide photoelectrode for a solar battery, in particular a method for preparing a cadmium sulfide quantum dot sensitized porous titanium dioxide photoelectrode. Background technique

[0002] As the global energy crisis is getting worse, people are eager to find sustainable clean energy. Solar energy, as an inexhaustible natural energy source, has increasingly attracted the attention of countries all over the world. Compared with traditional silicon solar cells, dye-sensitized nanocrystalline solar cells have low cost and easy fabrication, and have become a research hotspot of scholars from all over the world. In the preparation of dye-sensitized nanocrystalline solar cells, one of the key steps is how to sensitize the titanium dioxide film.

[0003] There are two main methods for traditionally preparing inorganic semiconductor quantum do...
