  • Patent number: 9657385
    Abstract: 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 VO2 thin 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 VO2 thin 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.

  • Patent number: 9442313
    Abstract: A thermochromic window, the sunlight transmittance of which is adjustable depending on temperature, and a method of fabricating the same. The thermochromic window includes a substrate, a plurality of nanodots formed on the substrate, and a thermochromic thin film coating the substrate and the nanodots. The thermochromic thin film is made of a thermochromic material. The thickness of the thermochromic thin film disposed on the substrate is smaller than the thickness of the thermochromic thin film disposed on the nanodots.

  • Patent number: 8988758
    Abstract: A thermochromic window doped with a dopant and a method of manufacturing the same. The thermochromic window includes a substrate and a thermochromic thin film formed on the substrate. The thermochromic thin film has a thermochromic material doped with a dopant, the concentration of the dopant gradually decreasing in a depth direction from one surface of the upper surface and the undersurface of the thermochromic thin film. The thermochromic window has a high level of visible light transmittance and high phase change efficiency while having a low phase transition temperature.

  • Patent number: 8801905
    Abstract: A thermochromic substrate and a method of manufacturing the same, in which the crystallinity of a thermochromic layer can be improved. The method includes the steps of forming a pre-thermochromic layer on a glass substrate by coating the glass substrate with pure vanadium, forming a seed layer by heat-treating the pre-thermochromic layer, and forming a thermochromic layer by coating the heat-treated seed layer with a vanadium dioxide (VO2) thin film.

  • Publication number: 20120263930
    Abstract: A thermochromic substrate and a pair-glass with a thermochromic thin film, which increases the efficiency with which solar energy is transmitted and blocked. The thermochromic substrate includes a base substrate, a thermochromic thin film coating the base substrate, and a high-refractivity thin film coating the thermochromic thin film. The high-refractivity thin film shifts the reference wavelength in the infrared range, at which the variance in the transmittance due to the phase transition does not exceed 0, to a shorter wavelength. The efficiency with which solar energy is transmitted and blocked is increased, thereby decreasing the load of cooling and heating a building.
