Electrochromic glass refers to the optical properties of the material (reflectance, transmittance, absorptivity, etc.) under the action of external electric field, stable and reversible color changes occur, and the appearance is shown as reversible color and transparency changes.
Electrochromic glass has the modulability of light absorption through an electric field, selectively absorbing or reflecting external thermal radiation and internal thermal diffusion, reducing the need for office buildings and residential buildings to stay cool in summer and warm in winter without consuming large amounts of energy. At the same time to improve the intensity of natural light, anti - peep purposes. It is a developing direction of energy-saving building materials to solve the problem of urban light pollution.
