Fabrication and optimization of efficient electrochromic electrodes and devices

Abstract

Various aspects associated with ‘nanotechnology’ have touched almost every sphere of our day-to-day life. Some of the modern-day gadgets like supercapacitors, batteries, solar panels, electrochromic devices (ECDs) etc. are doing their bit to combat the crisis. Electrochromism or electrochromic (EC) effect is the phenomenon of displaying a visible change in optical property under electrical stimuli and the materials displaying such effect are classified as EC materials (ECM). Spanning around a large range of materials from inorganic to organic and also composites, these materials possess an ability to change their intrinsic band gap structure which visibly results in a change of color thus offering them potential industrial applications. The basic structure of an ECD has a generic five layered design wherein electrochromic materials are chosen on basis of compatibility and the resultant devices are assessed in terms of few established parameters.
