Abstract: Electrochromic devices are disclosed which may be used for large surface area applications. The devices utilize optical tuning to minimize optical interference between layers of the structure and to maximize uniform optical transparency. Optical tuning also enables transparent conductive oxide layers to be replaced by thin conductive metal layers, thereby reducing the overall thickness of these devices and facilitating the manufacturing process.

Abstract: Electrochromic devices applied to a substrate are disclosed, including an electrochromic electrode layer, a counterelectrode layer, and an ion-conducting layer sandwiched between those two layers and electrically isolating them from each other, in which the ion-conducting layer is substantially uniform across the substrate and comprises an inorganic superstructure with associated organic material and with a microstructure which facilitates the transfer of ions. Methods for producing these devices are also disclosed, including depositing the ion-conducting layer on the substrate in the form of a solution, and effecting gelation of that solution.

Abstract: The invention provides for the simplified production of chromogenic devices, including relatively large scale devices in panel form. One or more of the layers of the invention are formed from heated, hydrolyzed gel reaction product of one or more dissolved organo-inorganics, such as alkoxides, which may be metallic. The invention includes an ion-conducting layer which comprises a lithium based ceramic material containing residual organic impurities.

Abstract: Processes for forming stable electrodes for use in electrochromic devices are disclosed including a stable electrode, a second electrode, and an ion-conducting layer therebetween, the processes include placing the stable electrode in an ion-conducting solution, placing a source of ions capable of chemically reducing the stable electrode in the ion-conducting solution, causing the ions and associated electrons to migrate to and chemically reduce the stable electrode, and forming an ion-conducting layer on the stable electrode from the ion-conducting solution.

Abstract: A chromogenic device with a chromogenic material facing a conductive layer, in which the transmission of incident radiation through the conductive layer and the chromogenic material is enhanced. The enhancement is achieved by adjusting indices of refraction of layers embracing the conductive layer.
