  • Publication number: 20200301233
    Abstract: Certain example embodiments of this invention relate to electrochromic devices (100, 1500), assemblies incorporating electrochromic devices, and methods of making the same. Highly-durable electrochromic devices include tungsten oxide (e.g., WO3 or other suitable stoichiometry) films (102, 1510) prepared using high-rate bias-enhanced sputter deposition. The sputtering is performed in a low-pressure (e.g., 1 mTorr) environment, and the biasing is very high (e.g., greater than ?400 V, more preferably greater than ?500 V), which causes high energy ion bombardment that in turn leads to partial nanocrystallization of the WO3 matrix, while simultaneously generating the porous microstructure desirable for ionic diffusion.
