  • Patent number: 10741708
    Abstract: According to some embodiments, the present invention provides a novel photovoltaic solar cell system from photovoltaic modules that are vertically arrayed in a stack format using thin film semiconductors selected from among organic and inorganic thin film semiconductors. The stack cells may be cells that are produced in a planar manner, then vertically oriented in an angular form, also termed herein tilted, to maximize the light capturing aspects. The use of a stack configuration system as described herein allows for the use of a variety of electrode materials, such as transparent materials or semitransparent metals. Light concentration can be achieved by using fresnel lens, parabolic mirrors or derivatives of such structures. The light capturing can be controlled by being reflected back and forth in the photovoltaic system until significant quantities of the resonant light is absorbed.
    Type: Grant

  • Patent number: 9705103
    Abstract: In various embodiments, optoelectronic devices are described herein. The optoelectronic device may include an optoelectronic cell arranged so as to wrap around a central axis wherein the cell includes a first conductive layer, a semi-conductive layer disposed over and in electrical communication with the first conductive layer, and a second conductive layer disposed over and in electrical communication with the semi-conductive layer. In various embodiments, methods for making optoelectronic devices are described herein. The methods may include forming an optoelectronic cell while flat and wrapping the optoelectronic cell around a central axis. The optoelectronic devices may be photovoltaic devices. Alternatively, the optoelectronic devices may be organic light emitting diodes.

  • Patent number: 8248305
    Abstract: The present disclosure describes antennas based on a conductive polymer composite as replacements for metallic antennas. The antennas include a non-conductive support structure and a conductive composite layer deposited on the non-conductive support structure. The conductive composite includes a plurality of carbon nanotubes and a polymer. Each of the plurality of carbon nanotubes is in contact with at least one other of the plurality of carbon nanotubes. The conductive composite layer is operable to receive at least one electromagnetic signal. Other various embodiments of the antennas include a hybrid antenna structure wherein a metallic antenna underbody replaces the non-conductive support structure. In the hybrid antennas, the conductive composite layer acts as an amplifier for the metallic antenna underbody. Methods for producing the antennas and hybrid antennas are also disclosed. Radios, cellular telephones and wireless network cards including the antennas and hybrid antennas are also described.
