Title:
ELECTROCHROMIC ELEMENT, SMART WINDOW, AND METHOD FOR DRIVING ELECTROCHROMIC ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/189194
Kind Code:
A1
Abstract:
This electrochromic element is provided with: a first transparent electrode and a second transparent electrode that face each other; a nanocrystal layer that is provided on the second transparent electrode-side surface of the first transparent electrode and that contains a plurality of metal oxide nanoparticles; an electrolytic layer that is provided between the nanocrystal layer and the second transparent electrode; and a control unit that controls a voltage to be applied between the first transparent electrode and the second transparent electrode. In a first case for changing the transmission spectrum of the nanocrystal layer by switching the voltage to be applied from a prescribed first voltage VA to a second voltage VB which is different from the first voltage VA, the control unit gradually changes the voltage to be applied from the first voltage VA to the second voltage VB. In a second case for changing the transmission spectrum of the nanocrystal layer by switching the transmission spectrum of the nanocrystal layer by switching the voltage to be applied from the second voltage VB to the first voltage VA, the control unit gradually changes the voltage to be applied from the second voltage VB to the first voltage VA.
