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.
