Sol-gel materials for smart electrochromic devices

Abstract Electrochromic devices have attracted increasing interest both from academia and industry. These devices are crucial for smart window technology. Currently the fabrication of large area devices for application in architectural glazing for the next generation of energy-efficient sustainable buildings is a hot research topic. This technological solution will reduce energy consumption in buildings, increase the indoor thermal/optical comfort for occupants, and improve outdoors view across different climate regions. Classical electrochromic devices rely on the use of electrochromic oxides. In this context the sol-gel process has emerged as an extremely versatile route to prepare, not only oxide coatings with improved performance, but also electrolytes with tailored properties. This chapter reviews the progress that has taken place since the first report of an all sol-gel electrochromic device was published, highlighting the latest achievements and main prospects of this exciting field of research.
