Abstract: An article can include a non-light-emitting, variable transmission device and a coating disposed between the non-light-emitting, variable transmission device and an ambient outside the article. In an embodiment, the article has a ΔE of at most 6.5. In another embodiment, the coating includes a plurality of layers including a first layer having a refractive index of at least 2.2 and a thickness of at least 10 nm. The coating can be used to help reduce color differences seen when the non-light-transmitting, variable transmission device is taken to different transmission states. In a particular embodiment, the coating can provide a good balance between color difference and luminous transmission.

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.

Abstract: A method can be used to control the operation of one or more non-light-emitting, variable transmission devices. In an embodiment, a method of operating a plurality of non-light-emitting, variable transmission devices can include receiving requests for requested visible transmittance for the non-light-emitting, variable transmission devices; determining operating parameters for the non-light-emitting, variable transmission devices; and operating the non-light-emitting, variable transmission devices at the operating parameters, wherein the operating parameters for the non-light-emitting, variable transmission devices are different. In another aspect, the method can include operating the non-light-emitting, variable transmission device at a first operating parameter for a time period, wherein the operating parameter corresponds to an intermediate visible transmittance; generating a characterization parameter based at least part on the voltage and current measurements that are obtained during the time period; and controlling the non-light-emitting, variable transmission device period based at least in part on the characterization parameter.

The assembly includes an insulated glazing unit including a variably transmissive glazing, a photovoltaic module attached to the insulated glazing unit and electrically coupled to the variably transmissive glazing, and a control module having a control circuit for controlling transmissivity of the glazing and a battery for providing power to the glazing. The photovoltaic assembly is attached to an exterior face portion of the insulated glazing unit, and a control module is attached to an interior face portion of the insulated glazing unit. Each module may extend from a first end of the insulated glazing unit to an opposing second end of the insulated glazing unit, wherein the length of the module being substantially the same as the distance between the first and second ends of the insulated glazing unit.

Abstract: An apparatus can include an electrochromic device configured to be maintained a continuously graded transmission state. When using the apparatus, the electrochromic device can be switched from a first transmission state to a continuously graded transmission state and maintained in the continuously graded transmission state. The current during switching can be higher than current during maintaining the continuously graded transmission state. In an embodiment, the grading can be reversed to provide a mirror image of the grading. In another embodiment, at least 27% and up to 100% of the electrochromic device can be in a continuously graded transmission state. The control device can be located within an insulating glass unit, adjacent to the insulating glass unit, or remotely from the insulating glass unit. In a further embodiment, a gap between bus bars can be used to form a portion of the electrochromic device that can be continuously graded.

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.

Abstract: An electrochromic device is structured to selectively switch separate regions to separate transmission levels, based at least in part upon different transport rates of different charged electrolyte species in the separate regions. Charged electrolyte species can be introduced in various regions of one or more electrochromic stack layers, including a counter-electrode layer, ion-conducting layer, and electrochromic layer. The charged electrolyte species can have different transport rates, so that a distribution of one species introduced in some regions move between layers and different rates relative another distribution of another species introduced in some regions. A species can be introduced, in one or more regions, in one or more particular distributions associated with a particular transmission pattern to structure the electrochromic device to selectively switch to the particular transmission pattern. Species can be introduced via various processes, including ion implantation, chemical diffusion, etc.
