  • Patent number: 9720298
    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: 8764951
    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. 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.

  • Patent number: 8736940
    Abstract: A method of forming a mirror reflective element assembly includes providing front and rear substrates and establishing a curved recess at a second surface of the front substrate and establishing a mirror reflector coating at the curved recess. An uncured seal is dispensed on a dispensing surface and has a first gap between terminal ends of said seal. The uncured seal is dispensed substantially around a principal reflecting region and a spotter region and defines a second gap between spaced apart portions of the uncured seal at an outboard region of the spotter region. A portion of the uncured seal is dispensed across the spotter region. The first gap provides a fill port for said mirror reflective element assembly when the front and rear substrates are mated together, and the second gap provides a vent port for the spotter cavity when the front and rear substrates are mated together.

  • Patent number: 8693078
    Abstract: This invention contemplates integrating laser scribing/patterning the component layers of electrochromic devices by directly removing (ablating) the material of the component layers. To minimize redeposition of laser ablated material and particulate formation on device surfaces a number of approaches may be used: (1) ablated material generated by the focused laser patterning may be removed by vacuum suction and/or application of an inert gas jet in the vicinity of the laser ablation of device material; (2) spatial separation of the edges of layers and patterning of lower layers prior to deposition of upper layers; and (3) the laser patterning step may be performed by a laser beam focused directly on the deposited layers from above, by a laser beam directed through the transparent substrate, or by a combination of both.
