Abstract

The invention provides a method and device for continuously preparing a transparent conductive film, and the method comprises the steps: carrying out the magnetron sputtering of an intrinsic ZnO filmlayer on a substrate after the deposition of a buffering layer, and then carrying out the magnetron sputtering of an Al-doped ZnO transparent conductive film layer; wherein a target material adopted by the magnetron sputtering intrinsic ZnO film layer is ZnO doped with 0.1-0.5 wt% of Al, the pressure of a cavity is 0.134-0.412 pa, the flow rate of introduced Ar gas is 20-50 sccm, and the flow rateof introduced oxygen gas is 13-20 sccm. By adopting the method provided by the invention, the light transmittance can be improved. The prepared transparent conductive film is good in uniformity and small in color difference.

Description

technical field [0001] The invention relates to the technical field of manufacturing transparent conductive films, in particular to a method and device for continuously preparing transparent conductive films. Background technique [0002] With the development of material science, transparent conductive films have been widely used in semiconductors, new energy and other devices due to their unique properties. The common ones are SnO 2-x 、In 2 o 3-x , ZnO, etc. Compared with metal transparent films, semiconductor transparent films have the advantages of high transparency, good mechanical properties, and strong film adhesion. [0003] For CIGS thin-film solar cells, considering the film-forming temperature, lattice and bandgap matching, economy, environmental friendliness and other reasons, the transparent conductive film usually used for the window layer is ZnO. The structure of CIGS thin film solar cells is as follows figure 1 shown. [0004] In order to improve the ef...
