Abstract
A layer of electrochromic material is on a substrate. An acid electrolyte is on the layer of electrochromic material. An indium electrode is utilized to produce coloration in the layer of electrochromic material without the need for any external electrical power. If a conductor layer is disposed between the substrate and the layer of electrochromic material, the device operates under a biasing voltage with substantially no polarization.
