Oxide-Based Electrochromics: Advances in Materials and Devices

Abstract

ABSTRACTElectrochromic (EC) devices are able to vary their throughput of visible light and solar energy by the application of a voltage. They are of much interest for “smart” windows in buildings and are able to create energy efficiency, occupant well being, and security. This paper gives a survey over oxide-based EC device technology and also presents some recent advances regarding EC thin films of mixed metal oxides, nanoparticle-containing electrolytes to join these films, and metal-based transparent electrical conductors needed to apply the voltage.
