Abstract

The invention provides a method for preparing a transparent conductive film material and relates to the preparation of the conductive film material. The invention adopts a medium-frequency reaction magnetic control sputtering system, washing and etching are carried out in a plasma by controlling a basal body before preparation, a metal Al target with higher purity and a ZnO target with high purity are adopted in the preparation process to carry out double-target co-sputtering, the double-target co-sputtering is aided by the plasma, a plasma etching technique is carried out after the preparation is finished, and the problem that the transparent conductive film with higher light transmittance and lower resistivity can not be obtained by low-temperature sedimentation is solved by controlling oxygen loss. The invention is simple and easy, effectively solves the problem that the proportion of metal elements is uncontrollable, has no pollution and simple technology, can use the prior ITO production line, can realize industrialized production without upgrading and reconstructing and has important research value and extensive application prospect, and all the raw materials are relatively common.

Description

technical field [0001] The invention relates to the preparation of a transparent conductive thin film material, in particular to a preparation method of a transparent conductive thin film material with high light transmittance, low resistivity, low cost and low temperature deposition. Background technique [0002] Transparent conductive oxide (TCO) thin films have been extensively studied and applied in many fields such as solar cells, liquid crystal displays, thermal mirrors, and energy-saving building glass due to their excellent photoelectric properties. Indium tin oxide (ITO) coated glass is a very mature product, which has the characteristics of high transmittance, firm film layer and good conductivity. It was initially used in the front electrode of photovoltaic cells. However, with the improvement of light absorption performance requirements, TCO glass must have the ability to improve light scattering, but it is difficult for ITO coating to achieve this, and the lase...
