WO3 Applied for Complementary Electrochromic Window

WO3 can be used to prepare an electrochromic film, which is applied to assemble a complementary electrochromic window. And the prepared electrochromic device is often used as an energy-saving window for studying the possibilities of practical application. But why has tungsten oxide smart window not been widely used? Because it still needs to solve some problems. For example, at present, there are still some problems in the long-term operational stability of electrochromic devices.

When it runs hundreds of times, the electrochromic device locally generates bubbles, and these bubbles grow at a slow rate. It is generally considered that this is the moisture remaining in the electrolyte, which is decomposed in an external electric field to generate a gas. In addition, a possible source of bubbles is the instability and degradation of the polymer electrolyte. From an application point of view, it is necessary to assemble the electrochromic device in a waterless environment.
