Abstract: Chromogenic materials and devices allow the construction of glazings whose throughput of visible light and solar energy can be varied depending on the application of an electrical voltage or temperature. These glazings are of much interest for energy efficient buildings and are able to create energy efficiency along with indoor comfort. This paper outlines the basics of electrochromic and thermochromic technologies with foci on functional principles, materials, device and manufacturing technology, and selected results from research and development.

Abstract: Electrochromic (EC) device technology can be used for modulating the transmittance of visible light and solar radiation in windows in buildings as well as for other see-through applications. This paper emphasizes the great energy savings that can be achieved in the built environment, jointly with improved indoor comfort for the users of the building. Manufacturing aspects are considered with particular focus on potentially low-cost methods possible to implement with roll-to-roll technology. In particular the paper discusses recent work on foil-type devices embodying sputter deposited WO3 and NiO-based films joined by a polymer electrolyte.
