Abstract:
The disclosure provides for an electrochromic element comprising a first substrate and a second substrate. The first substrate comprises a first surface and a second surface. The second substrate comprises a third surface and a fourth surface. The first substrate and the second substrate form a cavity have an electrochromic medium disposed therein. A dielectric coating is disposed on the fourth surface and is configured to provide for improved transmittance of the electrochromic element in the near infrared (NIR) range, wherein the near infrared transmittance exceeds the visible transmittance.
