ABSTRACT:
An improved ion conductor layer for use in electrochromic devices and other applications is disclosed. The improved ion-conductor layer is comprised of at least two ion transport layers and a buffer layer, wherein the at least two ion transport layers and the buffer layer alternate within the ion conductor layer such that the ion transport layers are in communication with a first and a second electrode. Electrochromic devices utilizing such an improved ion conductor layer color more deeply by virtue of the increased voltage developed across the ion conductor layer prior to electronic breakdown while reducing the amount of electronic leakage. Also disclosed are methods of making electrochromic devices incorporating the improved ion conductor layer disclosed herein and methods of making ion conductors for use in other applications.
