Manufacturing of electrochromic devices
First Claim
1. Method for manufacturing of electrochromic device, comprising the steps of:
- providing a first sheet comprising a first plastic substrate at least partially coated with a first electron conducting layer and a first electrochromic layer;
providing a second sheet comprising a second plastic substrate at least partially coated with a second electron conducting layer and a counter electrode layer;
laminating an electrolyte layer interposed between said first sheet and said second sheet into an electrochromic laminate sheet (30); and
defining at least a major part of an interior portion, in a lateral direction, of at least one electrochromic device by forming a seal through said electrochromic laminate sheet at a distance from a peripheral edge of said first sheet and from a peripheral edge of said second sheet, thereby obtaining an interior portion of each one of said at least one electrochromic device having a size smaller than said first sheet and said second sheet.

Abstract
A manufacturing method of electrochromic devices (10) includes the steps of providing a first and second sheet including a first (22) and second (24) plastic substrate, respectively, at least partially coated with a first (12) and second (14) electron conducting layer, respectively. The first sheet is at least partially coated with a first electrochromic layer (16). The second sheet is at least partially coated with a counter electrode layer (18). The first and second sheets are laminated with an electrolyte layer (20) interposed in-between into an electrochromic laminate sheet (30). The electrochromic device is at least partially defined by forming a seal (50) through the electrochromic laminate sheet (30) at a distance (D) from a peripheral edge (31). The distance (D) is preferably larger than the mean diffusion lengths of oxygen, water or an electrolyte component in the electrolyte during a predetermined time period.
