Progress in Oxide-based Electrochromics: Towards Roll-to-roll Manufacturing

Abstract [en]

Electrochromic devices allow the transmittance of visible light and solar energy to be varied between widely separated extrema. Such devices have large potential applications for energy efficient and comfort enhancing fenestration. A typical device has a centrally positioned electrolyte connecting two electrochromic oxide layers (one with anodic coloration and another with cathodic coloration), and this three-layer stack is positioned between thin films serving as transparent electrical conductors. The optical properties are modified when charge is shuttled between the electrochromic layers. The first part of this paper reviews recent progress regarding electrochromic materials, transparent conductors, and electrolytes with a focus on work in the author's research division. The second part of the paper discusses roll-to-roll manufacturing of electrochromic foil-based devices and presents experimental data. The paper is ended with some comments on the combination of electrochromics and thermochromics in order to produce "super windows" with optimized properties.
