Abstract:
1. A multi-cell electrochromic device, comprising: a plurality of solid-state electrochromic cells arranged in an optical alignment, each electrochromic cell being separated from an adjacent electrochromic cell in the optical alignment by a transparent conductive layer that is shared by the two adjacent electrochromic cells, a first electrochromic cell of the plurality of solid-state electrochromic cells comprising: a second electrochromic cell of the plurality of solid-state electrochromic cells comprising: each electrochromic layer comprises tungsten oxide WO each counter electrode layer comprises nickel oxide NiO, tungsten-doped nickel oxide, or iridium oxide IrO each ion conductor layer comprises silicon oxide SiO a first voltage being applied between the first transparent conductive layer and the shared transparent conductive layer, and a second voltage being applied between the shared transparent conductive layer and the second transparent conductive layer, the first and second voltages being different from each other.
