The aim of compiling this book has been to give a working knowledge of the important details of materials used in electrochromic devices, their characteristics, the process of manufacture, and uses in the industry to all researchers, scientists, and engineering students. This book is structured in a systematic manner and easy-to-read style while presenting fundamentals that can be quickly grasped by a beginner. We believe that it will serve as a comprehensive foundation and reference work for future studies within the rapidly expanding field of electrochromic materials and devices.

Electrochromic (EC) smart windows offer a well-designed approach to dynamically regulate daylight and solar radiation in multiple applications. Electrochromic materials can alter their properties, i.e., change their light transmittance state under the effect of a small electrical voltage or current. Different classes of materials such as transition metal oxides, metal-coordinated complexes, conjugated polymers, and organic compounds show this reversible switching mechanism, which make EC materials eligible for applications such as low-energy consumption displays, light-adapting mirrors in the automobile industry, and smart windows for which the amount of transmitted light and heat needs to be regulated.
