  • Patent number: 11217716
    Abstract: The invention relates to a method of interconnecting photovoltaic cells into a module by using a tape carrying tabbing wires. The tape makes possible to build modules at a reduced cost. In the tape method individual photovoltaic cells (1) are interconnected into modules by using electrical interconnecting conducting strips (21, 43, 52, 74a, 74b) carried by a tape (51). The strips are laid out on the topsides and backsides of the PV cells. The strips are cut in such a manner that the cells will be interconnected in series after lamination. The present invention concerns an improvement of the tape used in the tape method.

  • Patent number: 11196487
    Abstract: A system and method wherein electromagnetic radiation is used for free-space communication and wireless power transfer. The electromagnetic radiation used is preferably optical radiation. The optical free-space communication and wireless power transfer system includes an optical receiver device comprising an optical filter, a photodetector, and a photovoltaic cell, wherein a band of the incoming optical radiation is extracted by the optical filter and directed to the photodetector for communication data signal detection. The remaining optical radiation is converted by the photovoltaic cell into electrical power so that the harvested energy can be stored, used as the power source of the photodetector, or used as the power source of external devices.

  • Patent number: 11177765
    Abstract: Disclosed are methods and apparatus for providing portable solar array support systems. Embodiments of the invention include an apparatus that holds four 60-cell rooftop-grade solar panels and folds up into a relatively small portable device that easily fits in a garage or shed. When open, the panels are displayed at near the nominal angle to the sun for the region. Adjustable angle supports are available in alternative embodiments. Embodiments of the foldable solar array system are constructed from steel components, and feature proprietary integrated hinges to minimize the size and complexity of the system. The hinges are specially-cut sections of steel angle iron that force a solid stop point in the open or closed positions. These may be 90° hinges on the panel arms and swing arms, and may be 180° hinges on panel-to-panel hinges. The panel-to-panel hinges also allow for an offset based on the thickness of the solar panels and make the solar panels lay flat when open and stack face to face when closed.
