Electrochemical devices with plastic substrates

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.
