Abstract
An electrochromic device (1) comprises an electrochromic layered structure (10) having a first substrate sheet (21), a second substrate sheet (22), a first (23) and a second (24) electron conducting layer at least partially covering a respective substrate sheet, an electrochromic layer (25) and a counter electrode layer (26) at least partially covering a respective electron conducting layer and an electrolyte layer (30) laminated between and at least partially covering the first electrochromic layer and the counter electrode layer. The electrochromic layered structure also has an area (51, 52) in which the electrochromic layer or the counter electrode layer is not covered by the electrolyte layer. An electrode (41, 42) is soldered to the respective electron conducting layer through the electrochromic layer or the counter electrode layer.
