Abstract

The invention discloses a method for reducing power consumption of a transparent and conductive oxide thin film device by using micro structure adjustment and control. The method comprises a step of treating a transparent and conductive oxide thin film by adopting an SCCO2 method, specifically: adding deionized water into a reaction kettle of SCCO2 equipment; putting the transparent and conductiveoxide thin film into the reaction kettle, but enabling the transparent and conductive oxide thin film to be not in contact with the deionized water, and sealing the reaction kettle; heating the solution in the reaction kettle to 55 to 75 DEG C, pressurizing CO2 to 10 to 13 MPa, then continuously heating the solution to 120 to 150 DEG C, and carrying out thermal reaction for 30 to 90 min. According to the method for reducing the power consumption of the transparent and conductive oxide thin film device by using micro structure adjustment and control, the defects in the transparent and conductive oxide thin film are filled up by a simple and easy-to-control method; on the premise of not affecting the optical characteristic of the transparent and conductive oxide thin film, the electrical property of the transparent and conductive oxide thin film is effectively changed, so that joule heat of the transparent and conductive oxide thin film device, which is generated in a use process, is reduced.
