Description

technical field [0001] The invention relates to the technical field of electrochromism, in particular to an all-solid-state inorganic electrochromic device and a preparation method thereof. Background technique [0002] Electrochromic materials refer to materials whose optical properties (emission rate, transmission rate, absorption rate, etc.) will undergo stable and reversible changes after voltage is applied. Electrochromic materials include a wide range and can be roughly divided into two types: electrodeless electrochromic materials and organic electrochromic materials. Devices made of electrochromic materials are called electrochromic devices. Electrochromic devices have the advantages of high efficiency, low consumption, no pollution, and intelligence. All have broad application prospects. [0003] Electrochromic devices generally include a transparent conductive layer, an electrochromic layer and an electrolyte layer, and are supported by a transparent substrate, o...
