Nanostructured electrochromic materials for smart switchable windows This book focuses on next generation smart windows which can change their optical physical properties by reflecting and or transmitting incoming light radiation to attain comfortable indoor temperatures throughout the year. The book will address different techniques and materials used in smart windows in a simple way including the basic principles materials synthesis and thin film fabrication optical and electrochemical characterization techniques followed in laboratories and in industry. The application oriented perspective of the book will make it suitable to study solar energy conversion where research in nanomaterials can be extended to smart window applications
