Abstract
(EN)
An electrochromic article (400) is provided. The article includes a first glass sheet (402) having a first main surface and a second main surface; a second glass sheet (404) having a third main surface and a fourth main surface, the third main surface facing the second main surface; an electrochromic film (410) disposed between the second main surface and the third main surface, the electrochromic film having a fifth main surface facing the second main surface, a sixth main surface facing the third main surface, and a minor surface separating the fifth and sixth main surfaces; a first polyvinyl butyral (PVB) layer (406) disposed on the second main surface, intermediate the second main surface and the electrochromic film; a second PVB layer (408) disposed on the third main surface, intermediate the third main surface and the electrochromic film; and at least one barrier layer (412) separating the electrochromic film from the first and second PVB layers.
