Method for preparing electrochromic device

Abstract

The invention relates to a method for preparing an electrochromic device. The preparation method comprising the steps: (1), preparing a first transparent conductive layer; (2), preparing an electrochromic layer; to be specific, plating the surface of the first transparent conductive layer with an electrochromic film by using a plasma vacuum film-plating device to form an electrochromic layer; (3),preparing an ion conducting layer; (4), preparing an ion storage layer; to be specific, plating the surface of the ion conducting layer with an ion storage layer film by using a plasma vacuum film-platingg device to form an ion storage layer; (5), preparing a second transparent conductive layer; (6), preparing an ion barrier layer; (7), preparing an isolation layer; and (8), carrying out laser electrode etching. The method has the following advantage: the electrochromic device prepared by the preparation method has characteristics of wide discoloration range, high fading state transparency and fast discoloration speed.

Description

technical field [0001] The invention belongs to the technical field of electrochromic device preparation, and in particular relates to a preparation method of an electrochromic device. Background technique [0002] Electrochromism refers to the phenomenon that optical properties (reflectivity, transmittance, absorptivity, etc.) undergo a stable and reversible color change under the action of an applied electric field. Electrochromic technology has been developed for more than 40 years. Electrochromic devices (Electrochromic Device, ECD) are widely used in smart windows, It has broad application prospects in fields such as displays, spacecraft temperature control and modulation, automotive non-glare rearview mirrors, and weapons and equipment stealth. [0003] As a new type of smart window, ECD-based glass can adjust the intensity of incident sunlight according to comfort requirements, effectively reduce energy consumption, and demonstrate a significant energy-saving effect....

Problems solved by technology

[0004] In the existing preparation methods of electrochromic devices, for the preparation of the electrochromic layer and the ion storage layer in the structure of the electrochromic device, the magnetron sputtering coating process is generally used for coating, but the electrochromic film produced by this preparation process There are certain defects in the electrochromic device: due to the inconsistency of the properties of the film in the sputtering area, the discoloration range of the electrochromic device is relatively narrow, the transparency of the faded state is not high, and the discoloration speed is relatively slow
