Description

technical field [0001] The invention relates to a preparation method and application of an electrochromic glass device, and belongs to the technical field of functional materials and devices. [0002] technical background [0003] Buildings will install a lot of glass windows for better lighting and ventilation. When the sunlight passes through the glass, the heat of the solar energy will also pass through the glass. The heat of the solar energy passing through the glass is the core factor that determines the indoor temperature of the building. Among them, the high light intensity and long time in summer can easily cause overheating in the building, thereby increasing the air-conditioning cooling load of the building; in winter, the light intensity is weak and the time is short, which will cause the indoor temperature to be too low. In order to obtain a suitable indoor temperature, the building needs to be heated or cooled. With the rapid development of urbanization in my co...
