Abstract

The hypothesis of resistance-limited device behavior and the efficacy of equivalent circuits in modeling the behavior of electrochromic devices are considered. Two types of electrochromic systems, both based on tungsten oxide, are investigated. One is an all-solid-state-stack device, and the other is an aqueous, three-electrode cell system. The general appropriateness of the resistance-limited hypothesis is well-demonstrated, implying that diffusive processes are not important kinetically. The results suggest that development of useful equivalent circuits for electrochromic devices, which would prove invaluable for systems integration, should be pursued aggressively.
