Abstract:
1. Method for manufacturing of curved electrochromic devices, comprising the steps of: providing a first sheet comprising a first thermoplastic substrate at least partially coated with a first electron conducting layer in a flat form; providing a second sheet comprising a second thermoplastic substrate at least partially coated with a second electron conducting layer in a flat form; coating said first sheet at least partially by a first electrochromic layer; coating said second sheet at least partially by a counter electrode layer; laminating an electrolyte layer interposed between said first sheet and said second sheet into an electrochromic laminate sheet; thermoforming said first sheet and said second sheet into a permanent final curved shape after at least said step of providing a first sheet and said step of providing a second sheet; and sealing said electrochromic laminate sheet; wherein said step of thermoforming is performed jointly on said first sheet and said second sheet before said step of sealing.
