Problems solved by technology

However, the chemical properties of silver, copper and other metal nanowires are relatively active, and they are easily oxidized by air or corroded by chemical substances, which will seriously damage the conductivity of the film. This is the main obstacle for the practical application of metal nanowire transparent conductive films.

Abstract

The invention discloses a method of preparing a carbon-coated metal nanowire conductive thin film. A certain amount of metal nanowires is dispersed in a glucose solution, and a hydro-thermal reaction is carried out in a condition of 160 to 200 DEG C for 1 to 5 hours. The metal nanowire is a gold, silver, copper and the like metal nanowire or an alloy and a mixture. The metal nanowire transparent conductive thin film can be prepared through spraying or a thin film transfer method. The method is simple and easy to operate, and the metal nanowire conductive thin film stability can be improved obviously, and the method can promote application of the metal nanowire transparent conductive thin film in the field of an optoelectronic device such as a solar cell.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a method for preparing a carbon-coated metal nanowire conductive film. Background technique [0002] Transparent conductive electrodes are important components of novel optoelectronic devices such as solar cells. Transparent conductive oxide (TCO) materials represented by indium tin oxide (ITO) and fluorine-doped tin oxide (FTO) are currently the most commonly used transparent conductive electrode materials. TCO materials have disadvantages such as high cost and poor flexibility. Therefore, it is necessary to seek cheaper and flexible high-performance transparent conductive electrode materials. [0003] In recent years, transparent conductive films based on metal nanowires such as silver and copper have attracted extensive research. They have good electrical conductivity, light transmission and flexibility, and are easy to prepare and low in cost. However, metal nanowires ...
