Abstract

The invention discloses an electrochromic device with a low-resistance transparent electrode structure. The electrochromic device includes an electrolyte layer having a first surface and a second surface facing opposite directions, an electrochromic layer disposed on the first surface of the electrolyte layer, a counter electrode layer disposed on the second surface of the electrolyte layer, the first transparent electrode layer is arranged on the surface, opposite to the electrolyte layer, of the electrochromic layer, and the second transparent electrode layer is arranged on the surface, opposite to the electrolyte layer, of the counter electrode layer, and the first transparent electrode layer and the second transparent electrode layer comprise a composite layer; an oxide-based electrode layer having a material selected from the group consisting of AZO, FTO, and ITO and a metal-based electrode layer having a material selected from the group consisting of silver nanowires (AgNW), PEDOT: PSS, graphene, and a metal mesh are laminated in the composite layer.

Description

technical field [0001] The present disclosure relates to an electrochromic device having a low-resistance transparent electrode structure, and more particularly, to an electrochromic device having a low-resistance transparent electrode structure that can be formed to have a thin thickness so that it can be applied not only to Between substrates made of glass, it can also be applied between flexible substrates. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] As technologies for realizing smart glasses with adjustable light transmittance, technologies using electrochromic (EC) materials, polymer dispersed liquid crystals (PDLCs), and suspended particle devices (SPDs) have been known. [0004] Among these technologies, a technology using an electrochromic material has an advantage of lower driving voltage and power consumption than those using PDLC and SPD. [0005] The t...
