Abstract

The invention relates to a p-type copper sulphide transparent conductive film preparing method, characterized in forming unimolecular film on transparent quartz glass substrate surface by silicane molecule chemical absorption, and then diping in the prepared precursor solution. By induction of the unimolecular film, by controlling growth temperature and time of the film and the proportions of components of the precursor solution, it can prepare films of different conductivities and transmittances. At room temperature, the conductivity of the film can reach above 105S / m, average transmittance of the film in visible light range reaches above 60% and the transmittance of the film in local range can reach above 80%. And it can prepare films on substrates with complex shapes, suitable for industrialized large area film production. And the prepared p-type CuxS transparent conductive film can be applied to flat panel displays, solar batteries, LEDs and other photoelectric devices.
