Electrochromic materials change optical properties (darken/lighten) in the presence of a small electric potential difference, making them suitable for many applications. By fabricating porous films from crystalline WO 3 nanoparticles (see figure), this state‐of‐the‐art technology has been profoundly advanced. Significantly enhanced durability, increased charge insertion, and better kinetics have been demonstrated with an economical deposition process suitable for large‐area applications.
