Abstract

The invention pertains to the technical field of organic/inorganic nano-composite material, in particular to a polythiophene-carbon nano-tube composite light sensitive thin film material and a preparation method thereof. The composite thin film material consists of carbon nano-tube and the polythiophene, which has higher light sensitivity, compatibility and thermal stability as well as excellent solubility, film forming and electro-optical properties. The storage stability of the nano-composite light sensitive thin film material and the dispersion uniformity of the carbon nano-tube in the polythiophene, etc. are significantly superior to a traditional physical method. The preparation method of the invention has the advantages of simple technique, high quality of paint film, high input-output ratio and low cost etc. Products prepared by the invention are new generation green and environment protective chemical products which can be applied to fields such as conductive materials, solar cell materials, photoconductive materials and photoelectric conversion materials, etc.

Description

technical field [0001] The invention belongs to the technical field of organic / inorganic nanocomposite materials, and in particular relates to a polythiophene-carbon nanotube composite photosensitive film material and a preparation method thereof. Background technique [0002] With the development of modern industry and the depletion of fossil energy, energy demand has become the focus of attention of all countries in the world. The development of various new energy sources and the development of light, cheap and high-quality power sources have become the goals that scientists are striving for. As we all know, solar energy is inexhaustible. However, as an industrial energy source, solar energy has the disadvantage of low energy density. In order to make full use of this cheap, environmentally friendly, and renewable new energy, it has always been the goal that people pursue to produce cheap, efficient, and large-area solar photovoltaic cells. [0003] At present, silicon-b...
