Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.

Thin-film devices and fabrication

A tintable window is described having a tintable coating, e.g., an electrochromic device coating, for regulating light transmitted through the window. In some embodiments, the window has a transparent display in the window's viewable region. Transparent displays may be substantially transparent when not in use, or when the window is viewed in a direction facing away from the transparent display. Windows may have sensors for receiving user commands and/or for monitoring environmental conditions. Transparent displays can display graphical user interfaces to, e.g., control window functions. Windows, as described herein, offer an alternative display to conventional projectors, TVs, and monitors. Windows may also be configured to receive, transmit, or block wireless communications from passing through the window. A window control system may share computational resources between controllers (e.g., at different windows). In some cases, the computational resources of the window control system are utilized by other building systems and devices.

Displays for tintable windows

Various embodiments herein relate to electrochromic devices and electrochromic device precursors, as well as methods and apparatus for fabricating such electrochromic devices and electrochromic device precursors. In certain embodiments, the electrochromic device or precursor may include one or more particular materials such as a particular electrochromic material and/or a particular counter electrode material. In various implementations, the electrochromic material includes tungsten titanium molybdenum oxide. In these or other implementation, the counter electrode material may include nickel tungsten oxide, nickel tungsten tantalum oxide, nickel tungsten niobium oxide, nickel tungsten tin oxide, or another material.

Electrochromic cathode materials

Electrochromic devices are fabricated using a particle removal operation that reduces the occurrence of electronically conducting layers and/or electrochromically active layers from contacting layers of the opposite polarity and creating a short circuit in regions where defects form. In some embodiments, the particle removal operation is not a lithiation operation. In some embodiments, the particle removal operation is performed at an intermediate stage during the deposition of either an electrochromic layer or a counter electrode layer.

Electrochromic laminates

Methods, apparatus, and systems for mitigating pinhole defects in optical devices such as electrochromic windows. One method mitigates a pinhole defect in an electrochromic device by identifying the site of the pinhole defect and obscuring the pinhole to make it less visually discernible. In some cases, the pinhole defect may be the result of mitigating a short-related defect.

Pinhole mitigation for optical devices

Electrochromic devices with multi-layer conductors including one or more of a defect mitigation insulating layer, a color tuning layer and metal layer pair, and a transparent conductive oxide layer.

Faster switching low-defect electrochromic windows

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.

Fabrication of low defectivity electrochromic devices

Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.

Electrochromic window fabrication methods

Electrochromic device () having at least one multi-layer conductor () with a metal layer () between a first transparent conductive oxide layer () and a second transparent conductive oxide layer () and optionally having one or more tuning layers adjacent the metal layer.

Faster switching electrochromic devices

A high-speed data communications network in or on a building includes a plurality of trunk line segments serially coupled to each other by a plurality of passive circuits configured to deliver signals to, and to receive signals from, one or more devices on, in, or outside the building, wherein the signals comprise data having a greater than 1 Gpbs transmission rate.

Sensing and communications unit for optically switchable window systems

The embodiments herein relate to electrochromic stacks, electrochromic devices, and methods and apparatus for making such stacks and devices. In various embodiments, an anodically coloring layer in an electrochromic stack or device is fabricated to include a heterogeneous structure, for example a heterogeneous composition and/or morphology. Such heterogeneous anodically coloring layers can be used to better tune the properties of a device.

Counter electrode for electrochromic devices

Techniques for transceiving radio frequency (RF) signals through a window of a building are disclosed, the window having a first surface facing an interior of the building. An antenna arrangement is attached to a building structure adjacent the first surface and the antenna arrangement includes one or more radiating elements configured to transceive the RF signals through the window. In some embodiments, the building structure is mullion. In some embodiments a window surface includes an electrochromic and/or low emissivity coating that is excluded from a region proximate to the radiating elements.
