  • Patent number: 11374139
    Abstract: A photovoltaic module incorporates a lamination including a back-sheet, an array of solar cells supported on the back-sheet, and a transparent protective covering over the array of solar cells. The solar cells are arranged in offset or staggered patterns on the back-sheet to present a more random and less rigid industrial appearance to an observer. In some cases, cleaved solar cell segments are arranged into groups that are staggered on the back-sheet. This allows for finer control of the net voltage produced by a module. In other embodiments, full single wafer solar cells are arranged into larger groups, which themselves are staggered on the back-sheet. In either case, the result is a photovoltaic module with an appearance that is more organic and acceptable to homeowners and architects than traditional modules having cells arranged in rigid aligned rows and columns.

  • Patent number: 11367800
    Abstract: Optically-thin, quantum-structured solar cells incorporating III-V quantum wells or quantum dots have the potential to revolutionize the performance of photovoltaic devices. Enhanced spectral response characteristics have been widely demonstrated in both quantum well and quantum dot solar cells using a variety of different III-V materials. To fully leverage the extended spectral response of quantum-structured solar cells, new device designs are disclosed that can both maximize the current generating capability of the limited volume of narrow band gap material and minimize the unwanted carrier recombination that degrades the voltage output.
