Abstract
An electrochromic device having excellent repetitive characteristics is realized. An electrochromic device includes a first transparent electrode arranged on a first substrate, a second transparent electrode arranged on a second substrate, and a nanocrystal layer arranged on the first transparent electrode. An electrolyte is interposed between the nanocrystal layer and the second transparent electrode. The first transparent electrode, the second transparent electrode, and the nanocrystal layer do not cause an oxidation-reduction reaction when a voltage is applied to modulate a transmission spectrum, and do not include an electrode that causes modulation of a transmission spectrum by an oxidation-reduction reaction when a voltage is applied.
Claims9
An electrochromic device that modulates a transmission spectrum by applying a voltage, comprising:
- a first transparent electrode arranged on a first substrate;
- a second transparent electrode arranged on a second substrate;
- and
- a nanocrystal layer arranged on the first transparent electrode, wherein
- the nanocrystal layer and the second transparent electrode are arranged to face each other,
- an electrolyte is interposed between the nanocrystal layer and the second transparent electrode, and
- the first transparent electrode, the second transparent electrode, and the nanocrystal layer do not cause an oxidation-reduction reaction when a voltage is applied to modulate a transmission spectrum, and do not include an electrode that causes modulation of a transmission spectrum by an oxidation-reduction reaction when a voltage is applied.
