Quasi-Solid-State Electrochromic Cells with Energy Storage Properties Made with Inkjet Printing.

In common commercially available electrochromic glass panes, the active materials such as WO and NiO films are typically deposited by either physical vapor or sputtering under vacuum. In the present studies, we report on the inkjet printing method to deposit both electrochromic and ion storage electrode layers under ambient conditions. An ion storage layer based on cerium modified TiO and electrochromic nanocrystalline WO were both prepared under the wet method and deposited as inks on conductive substrates.
