It relates to a thermo-responsive dual band electrochromic device, which is capable of selectively controlling the amount of sunlight radiation transmitted in the visible and in the near-infrared regions by operating under four distinct optical regimes, namely: fully transparent, visible blocking, near-infrared blocking, and fully blocking. The device can be regulated either by an electric stimulus, namely by controlling the sign and the intensity of the applied bias voltage, or by a thermal stimulus. In the latter the attenuation of incoming thermal radiation results increased as temperature increases. The thermo-responsive dual band electrochromic device comprises a first electrode consisting of a first transparent conductive substrate topped by a first electro-optically active layer and a second electrode consisting of a second transparent conductive substrate topped by a second electro-optically active layer separated by a temperature-dependent ion conductive layer consisting of a thermo-responsive polymer gel, an ion conductor and a plasticizer.

The present disclosure relates to a method for manufacturing a flexible electrochromic device, and more particularly, to a method for manufacturing a flexible electrochromic device that bonds an electrochromic part and a counter electrode part while solidifying a wet-coated electrolyte with ultraviolet rays, thereby being capable of eliminating the possibility of bubble generation in the electrolyte and improving transmittance characteristics and durability.

Composite assemblies are described that can be switched from a transparent state to a non transparent state, and in some examples even switched between different colors/reflectivities in the non transparent state. Switching between these states can be initiated by application of an electrical current to Ag carbon nanotube yarns in contact with an electrochromic electrolyte. The carbon nanotube yarns increase the efficiency with which electrons are provided to an electrolyte.

A method of making an electrochromic device, includes: providing an electrochromic layer comprising a p-type electrochromic material; providing an ion-storage layer comprising an n-type metal oxide; and tuning the ion-storage layer, the electrochromic layer, or both the ion-storage layer and the electrochromic layer, so that when the electrochromic device is operating, the ion-storage layer operates in a minimally color changing mode.
