Problems solved by technology

Although the transmittance of some p-type transparent conductive films in the visible light range is close to or even the same as that of n-type transparent conductive films, their conductivity still has an insurmountable gap with n-type materials so far.
[0004] There are many ways to prepare transparent conductive films, but all of them are to prepare transparent conductive film materials first, and then combine transparent conductive film materials with other methods such as magnetron sputtering, vacuum true plating, chemical vapor deposition, etc. The combination of substrates and substrates requires cumbersome steps and is difficult to achieve large-scale production. In view of this, it is necessary to develop a method for directly preparing transparent conductive films on a large scale.

Abstract

The invention relates to a p-type copper sulfide transparent conductive film and a preparation method. When the square resistance of the copper sulfide transparent conductive film is as low as 10 ohmsper square, the transmittance of the visible light range is up to 86%, and the optimum resistivity can reach up to 1.02*10<-4> Omega.cm; and copper sulfide contained in the p-type copper sulfide filmis a p-type semiconductor material with a band gap range of 1.5-2.0 eV. The preparation of the copper sulfide transparent conductive film comprises the operation steps of mixing an amine compound, asulfydryl compound and a copper precursor in a solvent for reaction to obtain a precursor reaction solution; carrying out film formation on the precursor reaction solution on a substrate via a wet processing technology, then heating the substrate to obtain the p-type copper sulfide transparent conductive film. The method can realize one-step preparation of the copper sulfide transparent conductivefilm, and the preparation cost is low. Macro preparation can be realized according to a dip coating method. The prepared copper sulfide transparent conductive film has low square resistance and hightransmittance, and the performance is close to that of an n-type transparent conductive film.

Background technique [0002] The transparent conductive film is a film that has both transparent and conductive properties, and is highly transparent in the visible light range and has good conductivity. Due to its transparent and conductive properties, it has great application value in thin-film solar cells, flat panel displays, light-emitting diodes, and low-emissivity glass. Transparent conductive films can be divided into n-type and p-type according to the type of conductive carriers. Although there are many types of transparent conductive films and they are widely used, most of them are only used as a single optical coating without further research. It is prepared as an active device, because most of the transparent conductive films are n-type materials, a...
