An integrated computerized control system is capable of automating phases of electrochromic glass configuration, commissioning and control using a database synchronized between a provider side (e.g. manufacturer) and a customer side (e.g. installation location). The control system may support an on-site commissioning process that better ensures that each particular piece of electrochromic glass is correctly matched to glass-specific information used to configure a respective controller to control the particular piece of glass having particular characteristics.

A computing system for mapping one or more panes on a structure is provided. The computing system may receive a first indication from a first pane. The first indication may be associated with a first identification (ID) unique to the first pane. The computing system may receive a second indication from a second pane. The computing system may determine a relative position of the first pane relative to a position of the second pane based on receiving the first indication and the second indication. The computing system may map the relative position of the first pane to the first ID.

The invention relates to glazing ( 1 ) comprising a first glazing sheet ( 10; 10 A, 10 B) forming a substrate on which at least one film of an electrochemical system ( 12 ) is formed, said system having optical and/or energy-related properties that are electrically controllable, a second glazing sheet ( 14 ) forming a counter-substrate, and a third glazing sheet ( 18 ). The substrate has characteristics that allow it to be obtained by being cut from a motherboard on which motherboard at least one film of the electrochemical system ( 12 ) is formed. The substrate is located between the counter-substrate ( 14 ) and the third glazing sheet ( 18 ) and is set back relative to the counter-substrate ( 14 ) and relative to the third glazing sheet ( 18 ) over the entire circumference of the substrate ( 10; 10 A, 10 B).

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.

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.

The present disclosure describes various processes of forming an electrochromic stack using at most one metallic lithium deposition station. In some aspects, a process may include depositing metallic lithium only within an electrochromic counter-electrode of an electrochromic stack. In some aspects, a process may include using a lithium-containing ceramic counter-electrode target to form an electrochromic counter-electrode and depositing metallic lithium only within or above an electrochromic electrode of the electrochromic stack. In some embodiments, a process may include using a lithium-containing ceramic electrode target, and optionally additionally depositing metallic lithium to add mobile lithium to the electrochromic stack. In some embodiments, a process may include using a single metallic lithium deposition station to deposit metallic lithium between an ion-conducting layer and an electrochromic electrode of the electrochromic stack.

An apparatus can include an electrochromic device. When using the apparatus, the electrochromic device can be switched from a first transmission state to a continuously graded state and maintained at continuously graded transmission state. An apparatus can include an active stack with a first transparent conductive layer, a second transparent conductive layer, an anodic electrochemical layer between the first and the second transparent conductive layers, and a cathodic electrochemical layer between the first and the second transparent conductive layers. The apparatus can further include a first bus bar electrically coupled to the first transparent conductive layer, a second bus bar electrically coupled to the second transparent conductive layer, where the second bus bar is generally non-parallel to the first bus bar, and a third bus bar electrically coupled to the first transparent conductive layer, where the third bus bar is generally parallel to the first bus bar.
