Electrochromic Patents (Class 359/265)
  • Patent number: 10347777
    Abstract: A method is provided that integrates an autonomous energy harvesting capacity in vehicles in an aesthetically neutral manner. A unique set of structural features combine to implement a hidden energy harvesting system on a surface of the vehicle to provide electrical power to the vehicle, and/or to electrically-powered devices in the vehicle. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below.

  • Patent number: 10088731
    Abstract: Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.

  • Patent number: 10088729
    Abstract: Conventional electrochromic devices frequently suffer from poor reliability and poor performance. Improvements are made using entirely solid and inorganic materials. Electrochromic devices are fabricated by forming an ion conducting electronically insulating interfacial region that serves as an IC layer. In some methods, the interfacial region is formed after formation of an electrochromic and a counter electrode layer, which are in direct contact with one another. The interfacial region contains an ion conducting electronically insulating material along with components of the electrochromic and/or the counter electrode layer. Materials and microstructure of the electrochromic devices provide improvements in performance and reliability over conventional devices. In addition to the improved electrochromic devices and methods for fabrication, integrated deposition systems for forming such improved devices are also disclosed.

  • Patent number: 10036930
    Abstract: An electro-optic assembly comprises an adhesive layer and a layer of electro-optic material. The adhesive layer comprises a polymeric adhesive material and an ionic material having either its cation or its anion fixed to the polymeric adhesive material. The ionic material reduces the volume resistivity of the polymeric adhesive material and is not removed upon heating to 50° C. In a similar electro-optic assembly comprising an adhesive layer and a layer of electro-optic material, the adhesive layer comprises a polymeric adhesive material which has been subjected to dialysis or diafiltration to remove organic species having a molecular weight less than about 3,500, so that the adhesive material has a content of N-methylpyrrolidone not exceeding 500 ppm based upon the total weight of the adhesive layer and layer of electro-optic material.

  • Patent number: 10009958
    Abstract: A transparent pane having an electrically heatable coating and at least one coating-free zone that can be used, for example, as a communication window, is disclosed. The electrically heatable coating is connected to two collecting electrodes, such that a supply voltage applied to the electrodes generates a heating current that flows via a heating field formed between the collecting electrodes, the heating field containing the coating-free zone whose zone-edge is formed, at least in sections, by the heatable coating. Other implementation details include subdivision of one of the two collecting electrodes into separated subregions, each connected, via an electrical supply line, to an additional electrode. In one case, the electrical supply line runs, at least in sections, in the coating-free zone, in a coating-free edge strip, in a subregion of the coating outside the heating field, and/or in the zone-edge. Methods for producing the transparent pane are also disclosed.

  • Patent number: 10001691
    Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.
