  • Patent number: 10396228
    Abstract: A solar concentrator module (80) employs a luminescent concentrator material (82) between photovoltaic cells (86) having their charge-carrier separation junctions (90) parallel to front surfaces (88) of photovoltaic material 84 of the photovoltaic cells (86). Intercell areas (78) covered by the luminescent concentrator material (82) occupy from 2 to 50% of the total surface area of the solar concentrator modules (80). The luminescent concentrator material (82) preferably employs quantum dot heterostructures, and the photovoltaic cells (86) preferably employ low-cost high-efficiency photovoltaic materials (84), such as silicon-based photovoltaic materials.

  • Publication number: 20130206219
    Abstract: Photovoltaic cells (22) of different materials may be integrated at the network (20) or panel level to optimize independent and cooperative efficiencies and manufacturing techniques of the different materials. The sizes and numbers of the photovoltaic cells (22) in the separate photovoltaic networks (20) may differ. Separate fabrication of the different photovoltaic networks (20) permits optimization of an interlayer material (110), which can be insulating or noninsulating and can include one or more of light-scattering or light-emitting particles, photonic crystals, metallic materials, an optical grating, or a refractive index grading. For example, adaptations of increased emitter layer thickness, lower sheet resistance, increased gridline spacing, smoother photovoltaic material surface, and/or increased AR coating thickness are made to a multicrystalline silicon photovoltaic cell (20) for optimization as a bottom network (20b) of a tandem solar module.

  • Publication number: 20120305860
    Abstract: The light conversion efficiency of a solar cell (10) is enhanced by using an optical downshifting layer (30) in cooperation with a photovoltaic material (22). The optical downshifting layer converts photons (50) having wavelengths in a supplemental light absorption spectrum into photons (52) having a wavelength in the primary light absorption spectrum of the photovoltaic material. The cost effectiveness and efficiency of solar cells platforms (20) can be increased by relaxing the range of the primary light absorption spectrum of the photovoltaic material. The optical downshifting layer can be applied as a low cost solution processed film composed of highly absorbing and emissive quantum dot heterostructure nanomaterial embedded in an inert matrix to improve the short wavelength response of the photovoltaic material. The enhanced efficiency provided by the optical downshifting layer permits advantageous modifications to the solar cell platform that enhances its efficiency as well.
