Electrochemical characteristics electrochromic devices

We must needs start this chapter by making the important observation that, although there is a surfeit of studies of the electrochromic properties of a wide variety of CPs in a laboratory environment, there is a dearth of studies of actual, practical devices. Furthermore, there is an even greater dearth of examples of commercial implementation of CP-based electrochromic devices. The tests in laboratory environments typically involve looking at the spectroelectrochemical characteristics of a CP film deposited chemically or electrochemically on a transparent conductive electrode such as ITO/glass in a liquid-electrolyte containing cell. A plethora of such studies have been cited in Chapter 3 earlier, and the reader is referred to these for an appreciation of the multitude of colors, dynamic ranges and other performance characteristics obtainable with CP-based electrochromics.
