  • Publication number: 20190036480
    Abstract: An electricity generating window includes a first glass pane, a second glass pane, and a photovoltaic device formed on an inner surface of the first glass pane or an inner surface of the second glass pane. The photovoltaic device includes a first transparent electrode layer, a second transparent electrode layer, and one or more active layers configured to transmit visible light and absorb ultraviolet or near-infrared light. In some embodiments, the electricity generating window also includes a spacer configured to separate the first glass pane and the second glass pane by a cavity. In some embodiments, the electricity generating window also includes one or more functional layers, such as an electrochromic layer or a low-E layer for reflecting infrared light.

  • Publication number: 20180138344
    Abstract: A photovoltaic module includes a first transparent electrode layer characterized by a first sheet resistance, a second transparent electrode layer, and a photovoltaic material layer. The photovoltaic material layer is located between the first transparent electrode layer and the second transparent electrode layer. The photovoltaic module also includes a first busbar having a second sheet resistance lower than the first sheet resistance. The first transparent electrode layer, the second transparent electrode layer, and the photovoltaic material layer have an aligned region that forms a central transparent area of the photovoltaic module. The central transparent area including a plurality of sides. The first busbar is in contact with the first transparent electrode layer adjacent to at least a portion of each of the plurality of sides of the central transparent area.
