  • Patent number: 10962856
    Abstract: Ion-storage layers for electrochromic devices (ECDs) that are tuned to be minimally color changing (MCC) during operation of the ECDs. In some embodiments, an ion-storage layer is composed of an n-type metal oxide that complements a p-type electrochromic (EC) layer, such as an EC layer made of a p-type EC polymer. In some embodiments, an ion-storage layer may be tuned to be MCC by configuring an ion-storage layer to have a total charge density that is higher than the total charge density of a corresponding EC layer or to have a coloration efficiency lower than the coloration efficiency of the corresponding EC layer, or both. Methods for preparing ion-storage layers are disclosed, including methods for creating highly structured metal oxide having reduced coloration efficiencies. ECD devices incorporating MCC ion-storage layers are also disclosed.

  • Patent number: 10935865
    Abstract: Controllers and control methods apply a drive voltage to bus bars of a thin film optically switchable device. The applied drive voltage is provided at a level that drives a transition over the entire surface of the optically switchable device but does not damage or degrade the device. This applied voltage produces an effective voltage at all locations on the face of the device that is within a bracketed range. The upper bound of this range is associated with a voltage safely below the level at which the device may experience damage or degradation impacting its performance in the short term or the long term. At the lower boundary of this range is an effective voltage at which the transition between optical states of the device occurs relatively rapidly. The level of voltage applied between the bus bars is significantly greater than the maximum value of the effective voltage within the bracketed range.
