Abstract

An all solid-state variable transmission electrochromic device has a source of charge compensating ions. An inorganic oxide counterelectrode film which on reduction with the accompanying insertion of the charge compensating ions increases its transmission of light of predetermined wavelength is separated from a primary electrochromic film which on reduction with the accompanying insertion of the charge compensating ions decreases its transmission of light of predetermined wavelength by an insulating electrolyte film that transports the charge compensating ions. First and second electrodes are contiguous with the inorganic oxide counter electrode film and the primary electrochromic film, respectively, and separated by the three films.

Fundamentals of electrochromism in metal oxide bronzes

Conference Haas, T; Goldner, R

The phenomenon of electrochromism as described here is clearly a property to be associated with a material. The material must be capable of reversible oxidation and reduction, and have an accompanying spectral change. However, since it requires a chemical change of oxidation state to occur, there must be a corresponding second material to serve as the source/sink of electrons and charge compensating ions. In short, electrochromism is observable only in a device, not in an isolated material. In its essence an electrochromic device is simply a reversible electrochemical cell, consisting of electronic conductors (the wires for an external electronic pathway),more »« less

Technical Report

The structure under development at EIC Laboratories consists of a multilayer stack of thin films, incorporating the two principal electrochemically active elements, the electrochromic (EC) and counter electrode (CE) layers, respectively. The EC layer changes from colorless to a state of reduced transmission on reduction while the CE layer has the opposite (complementary) behavior (or is colorless in both oxidized and reduced states). These are separated by an ion conducting electrolyte. The stack is completed with top and bottom transparent electrodes. The major achievements are as follows: (1) Tunable thermal emittance for the EC layer over a range of 0.2more »« less
