Problems solved by technology

Among them, the vacuum physical method mainly refers to the magnetron sputtering method, which can prepare dense and uniform transparent conductive films with good physical adhesion, but has high requirements for equipment and growth environment.

The chemical method is mainly the sol-gel method. The advantage of this method is that the production equipment is simple and it is easy to achieve uniform doping of multi-components. However, the physical adhesion between the conductive film and the substrate is poor and the high temperature treatment makes the substrate of the transparent conductive electrode tablets are restricted

For the preparation of patterned transparent conductive electrodes, tedious processes such as etching and developing are required.
