Abstract

Interest in the electrochromics research in the 80's was mainly directed towards potential applications for variable light transmission windows. Even though large-area electrochromic cells incorporating liquid electrolytes are being investigated, we focused on solid state devices. Such devices offer fewer fabrication problems in large-area applications. The solid electrolyte layer is a key component in the fabrication of the solid state windows. This layer must be transparent, electrochemically stable and display adequate ionic conductivity. Optical efficiencies of asymmetric solid state devices based on tungsten oxide as the electrochromic material and commercially available ionomers and polyelectrolytes - Naflon, poly(styrene sulfonic acid), and poly(2-acrylamido-2-methylpropanesulfonic acid), as the solid electrolyte layer are presented at room temperature and 90 C. Impedance behavior of this asymmetric system is discussed and compared with the behavior observed in other systems.
