  • Publication number: 20190155120
    Abstract: A non-light-emitting, variable transmission device can include a first substrate, a first transparent conductive layer, an electrochromic layer, a second transparent conductive layer, a second substrate; and an interlayer disposed between the first substrate and the second substrate. The non-light-emitting, variable transmission device is configured such that a failure of the non-light-emitting, variable transmission device is less likely than another non-light-emitting, variable transmission device in which the interlayer directly contacts the second transparent conductive layer and has a moisture content of at least 0.08 wt %. In an embodiment, the interlayer has a moisture content of at most 0.05 wt %.

  • Publication number: 20190079365
    Abstract: A non-light-emitting variable transmission device can include an active stack; a transparent conductive layer overlying the active stack; an antireflective layer overlying the transparent conductive layer and defining a hole; and a bus bar comprising a conductive tape that extends into the hole and contacts the transparent conductive layer. Proper selection of materials and design of a bus bar can allow an electrical connection to be made to the transparent conductive layer without the need to cut an underlying transparent conductive layer. A method of forming the non-light-emitting variable transmission device can include patterning the antireflective layer to define the hole that extends to the transparent conductive layer. Improved control in patterning allows the antireflective layer to be relatively thin and not remove too much of the underlying transparent conductive layer.

  • Publication number: 20190051570
    Abstract: A process for encapsulating an apparatus to restrict environmental element permeation between the apparatus and an external environment includes applying multiple barrier layers to the apparatus and preceding each layer application with a separate cleaning of the presently-exposed apparatus surface, resulting in an apparatus which includes an encapsulation stack, where the encapsulation stack includes a multi-layer stack of barrier layers. Each separate cleaning removes particles from the presently-exposed apparatus surface, exposing gaps in the barrier layer formed by the particles, and the subsequently-applied barrier layer at least partially fills the gaps, so that a permeation pathway through the encapsulation stack via gap spaces is restricted. The quantity of barrier layers applied to form the stack can be based on a determined probability that a stack of the particular quantity of barrier layers is independent of at least a certain quantity of continuous permeation pathways through the stack.

    Abstract: An electrochromic structure can include a substrate and an electrochromic residue disposed on the substrate. The electrochromic structure can include an electrochromic stack on the substrate. A process can be used to separate the structure. The process can include forming a filament in the substrate and applying a thermal treatment to the substrate. Forming a filament can be performed by applying a pulse of laser energy to the substrate. In a particular embodiment, a filament pattern including a plurality of filaments can be formed in the substrate. The substrate can include mineral glass, sapphire, aluminum oxynitride, spinel, or a transparent polymer.

  • Publication number: 20180299742
    Abstract: An electrochromic device is structured to restrict moisture permeation between an electrochromic stack in the device and an external environment. The electrochromic device includes conductive layers and one or more encapsulation layers, where the encapsulation layers and conductive layers collectively isolate the electrochromic stack from the ambient environment. The encapsulation layers resist moisture permeation, and at least the outer portions of the conductive layers resist moisture permeation. The moisture-resistant electrochromic device can be fabricated based at least in part upon selective removal of one or more outer portions of at least the EC stack, so that at least the encapsulation layer extends over one or more edge portions of the EC stack to isolate the edge portions of the EC stack from the ambient environment. The encapsulation layer can include one or more of an anti-reflective layer, infrared cut-off filter, etc.

  • Patent number: 9152001
    Abstract: One object of the present invention is to provide an electrochromic device having improved insulating film structure to reduce electrical leakage. The improved structure includes a lower conductive layer, upper transparent conductive layer, an electrochromic electrode layer, a counter electrode layer, and at least one ion-conductor layer sandwiched between the electrochromic electrode layer and the counter electrode layer. The lower transport conductive layer is scribed and the gap formed from the scribing is filled with the layer(s) formed above the lower conductive layer, such as the electrode layer formed directly above the lower conductive layer. The effective linewidth of the scribe is greater than the migration length of the lithium ions intercalated into the electrode layer, such that the electrode materials occupying the gap do not convert the electrode layer into an electrically conductive region.

  • Publication number: 20150253642
    Abstract: Several of the films that comprise various energy producing or control devices, for example, electrochromic devices, lithium batteries, and photovoltaic cells, are sensitive to moisture in some way. They may be especially vulnerable to moisture at particular stages during their fabrication. It may also be highly desirable during fabrication to be able to wash particulates from the surface. The particulates may be generated some aspect of the fabrication process, or they may arise from the environment in which the fabrication takes place. This invention shows ways to remove said particles from the surface without incurring the damage associated with typical washing processes, resulting in higher manufacturing yields and better device performance.
