1. An electrochromic device comprising:

  • a first substrate that is flexible or rigid and having a first shape, a first surface, and a second surface, the second surface comprising a first conductive material;

    a second substrate comprising a polymer that is flexible and configured to conform to the shape of the first substrate and having a first surface and a second surface, the first surface comprising a second conductive material; and

    a sealing member, joining the second surface of the first substrate to the first surface of the second substrate forming a chamber therebetween;

    wherein;

    the first conductive material comprises a first conductive nanowire coating, a first conductive metal mesh, or a first insulator/metal/insulator stack (IMI stack);

    the first surface, the second surface, or both the first surface and the second surface of the second substrate comprises an adhesion promotion layer;

    the first substrate comprises an ultraviolet light absorbing layer;

    the second surface is coated with a first polymer-based electrochromic film comprising an anodic material; and

    the chamber comprises a fluid medium containing a UV-curable gelling agent.
