Embodiment Construction

[0057] Described here are improved windows including transparent Photovoltaic (PV) modules. One or more visible transparent PV layers can be integrated into Insulated Glazing Units (IGUs) used in windows of buildings or other structures such as vehicles. A PV layer integrated into an IGU can be used to generate electricity for a building or other installation site by converting light outside the visible band (eg, Infrared (IR) or Ultraviolet (UV)) into electricity. By converting the IR light entering the IGU into electricity, the PV layer can help improve the overall thermal performance of the IGU, such as thermal emissivity and solar heat gain coefficient, thereby reducing heating and / or cooling costs of the building. Because the PV layer is substantially transparent to visible light, visible light from a light source (eg, the sun) can enter the building through the IGU with little loss to illuminate the building's interior. In various embodiments, the PV layer can also be i...

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 glasspane. 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 444577, filed January 10, 2017, entitled "WINDOW-INTEGRATED TRANSPARENT PHOTOVOLTAIC," the disclosure of which is incorporated herein by reference in its entirety for all purposes. technical field [0003] The present invention relates generally to the field of photovoltaic modules and devices, and more particularly to window-integrated transparent photovoltaic modules. Background technique [0004] Building-integrated photovoltaic (Photovoltaic, PV) technology has been applied to convert solar energy irradiated on buildings into electrical energy that can be used or stored in buildings or can be fed back to the grid. However, these techniques have not been widely used due to, for example, cost, opacity, and aesthetic issues associated with installing traditional PV cells in locations such as architectural windows.
