Title:
ELECTROCHROMIC ELEMENT AND SMART WINDOW
Document Type and Number:
WIPO Patent Application WO/2018/230557
Kind Code:
A1
Abstract:
This electrochromic element is provided with: first and second transparent electrodes facing each other; and a nano-crystalline layer provided on a second transparent electrode-side surface of the first transparent electrode. The transmission spectrum of the electrochromic element changes according to the applied voltage. Changes in the transmission spectrum involve changes in the transmittance of near-infrared light and visible light. When the state of the electrochromic element is switched from a first state having a relatively low transmittance of the near-infrared light to a second state having a relatively high transmittance of the near-infrared light, the changes in the transmission spectrum include: a first change in which the color of the transmitted light becomes a warm color; or a second change in which the color of the transmitted light does not become a cold color.
