Abstract
Electrochromic devices applied to a substrate are disclosed, including an electrochromic electrode layer, a counterelectrode layer, and an ion-conducting layer sandwiched between those two layers and electrically isolating them from each other, in which the ion-conducting layer is substantially uniform across the substrate and comprises an inorganic superstructure with associated organic material and with a microstructure which facilitates the transfer of ions. Methods for producing these devices are also disclosed, including depositing the ion-conducting layer on the substrate in the form of a solution, and effecting gelation of that solution.
