Abstract
A method for fabricating an electrochromic device having organic polymer substrates is described. Each substrate has a surface coated with an organic polymer primer coating onto which is deposited an electroconductive metal oxide film. An electrochromic material is deposited on one electroconductive film and a complementary electrochromic material is deposited on the other electroconductive film. The resultant two substrates are aligned with the electrochromic materials facing one another. A preformed sheet of an ion-conducting polymer is disposed between those electrochromic layers and the resulting sandwich autoclaved.
