Abstract

The invention discloses an electrochromic device, and in particular discloses a multi-layer structure of which a main body is transparent glass. A porous aerogel layer is packaged, conductive materials are coated on a specific substrate, and an electrochromic material is packaged among the conductive materials; voltage is applied to the conductive material layer, so that the characteristics of the electrochromic material can be changed; and moreover, photocatalyst materials can be coated on the outer side of the substrate, and a solar power supply layer is arranged, so that power can be supplied to the electrochromic device or the power can be supplied to other devices. According to another embodiment, an electrochromic composite material layer can be packaged between two adjacent substrates in the electrochromic device and has a composite structure consisting of aerogel and the electrochromic material.

Description

technical field [0001] The invention relates to an electrochromic device, in particular to an electrochromic device whose transparency can be changed by applying voltage. Background technique [0002] According to the known electrochromic technology, the materials used in it can change the reflectivity, transmittance and absorptivity of the electrochromic material under the action of an external electric field, and can produce stable and reversible color changes, such as color and transparency. between changes. [0003] Electrochromic materials can be divided into inorganic electrochromic materials and organic electrochromic materials. The typical representative of inorganic electrochromic materials is tungsten trioxide, while organic electrochromic materials mainly include polythiophenes and their derivatives, viologens, tetrathiafulvalenes, and metal phthalocyanine compounds. [0004] If the general portal glass uses known electrochromic materials to form a kind of smart...
