    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.

    Abstract: An apparatus can include a control device configured to select a scene from a collection of scenes for a window including electrochromic devices in response to receiving an input corresponding to state information. In another aspect, a method of operating an apparatus can include receiving an input corresponding to state information; and at a control device, in response to receiving the input, selecting a scene from a collection of scenes. The collection of scenes may be validated before using the scenes. The scenes may be validated based on physical configuration of the controlled space, preferences of the occupant, or the like. Still further, scenes can be changed to allow for the passage of time or an illusion of changing sky conditions when sky conditions are not changing. The apparatus and method can be simpler to understand and implement as compared to complex control strategies.

    Abstract: 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.

    Abstract: An electrochromic device can include a substrate; an electrochromic layer or a counter electrode layer over the substrate and including a mobile ion; a first transparent conductive layer over the substrate and including Ag. In one embodiment, the electrochromic device can include a barrier layer disposed between first transparent conductive layer and the electrochromic or counter electrode layer. In another embodiment, the electrochromic device can include means for preventing (1) the mobile ion from migrating into the first transparent conductive layer, (2) Ag from migrating into the electrochromic layer or counter electrode layer, or both (1) and (2). A process of forming an electrochromic device can include forming an electrochromic layer or a counter electrode layer over a substrate; forming a barrier layer; and forming a first transparent conductive layer over the substrate.
