A method of manufacturing a thermochromic substrate, with which transmittance can be increased. The method includes the steps of forming a first thin film as a coating on a base substrate, the refractive index of the first thin film being different from that of a VOthin film; forming a pre-thermochromic thin film by coating the first thin film with pure vanadium; forming a second thin film as a coating on the pre-thermochromic thin film, the refractive index of the second thin film being different from that of a VOthin film; and heat-treating a resultant stack that includes the base substrate, the first thin film, the pre-thermochromic thin film and the second thin film.

Method of manufacturing thermochromic substrate

A thermochromic window that can effectively insulate heat when warming is conducted in winter. The thermochromic window that includes a substrate, a thermochromic thin film formed on the substrate, and a transparent conductive film formed on at least one surface of the upper surface and the undersurface of the thermochromic thin film. The emissivity of the transparent conductive film is lower than the emissivity of the thermochromic thin film.
