Abstract

Electrochromic devices are multilayer structures comprised of 1) an electrochromic (EC) layer such as tungsten oxide, WO₃, 2) an ion storage (IS) layer or counter electrode (CE) such as nickel oxide, NiO, or iridium oxide, IrO_x, 3) an ion conducting (IC) layer such as tantalum pentoxide, Ta₂O₅, 4) and two transparent electron conducting layers separating the EC, IS and IC layers. A transmissive all-inorganic EC device which will be the subject of this paper is shown Figure 1.
