Publication number: 20130021659Abstract: 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.Type: ApplicationFiled: September 14, 2012Publication date: January 24, 2013Applicant: SOLADIGM, INC.Inventors: Robin Friedman, Sridhar Kailasam, Rao Mulpuri, Ron Powell, Dhairya Shrivastava

Publication number: 20130003157Abstract: 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. 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.Type: ApplicationFiled: September 11, 2012Publication date: January 3, 2013Applicant: SOLADIGM, INC.Inventors: Zhongchun Wang, Anshu Pradhan, Robert Rozbicki

Publication number: 20120327499Abstract: Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.Type: ApplicationFiled: April 25, 2012Publication date: December 27, 2012Applicant: SOLADIGM, INC.Inventors: Ronald M.

Publication number: 20120293855Abstract: 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.Type: ApplicationFiled: May 23, 2012Publication date: November 22, 2012Applicant: SOLADIGM, INC.Inventors: Dhairya Shrivastava, Anshu Pradhan, Stephen C.

Patent number: 8243357Abstract: Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition.Type: GrantFiled: May 11, 2011Date of Patent: August 14, 2012Assignee: Soladigm, Inc.Inventors: Mark Kozlowski, Eric Kurman, Zhongchun Wang, Mike Scobey, Jeremy Dixon, Anshu Pradhan, Robert Rozbicki
