Abstract

Solid-state flexible polymer-based electrochromic devices are fabricated continuously by stacking layers in one direction. This novel bottom-up approach with no need for a lamination step is realized through in situ photo-crosslinking of the electrolyte using a "curing-chamber" fitted to a roll-coater, which lowers the oxygen concentration at the electrolyte surface. This enables fully printed and 2D patterned organic electrochromics.

Keywords: electrochromic devices; in-situ photo crosslinking; slot-die coating; solid state electrolyte.
