Principle of Electrochromism
- © Fraunhofer-Institut für Silicatforschung ISC
Electrochromism involves electroactive materials that show a reversible colour change when a small DC voltage is applied. The potential causes redox reactions to take place in the electrochromic and ion storage layers, a process which is accompanied by ion migration across the ion-conducting layer to achieve charge compensation. The materials and physical composition of electrochromic devices can vary strongly.
