  • Patent number: 10383520
    Abstract: Embodiments of the present disclosure include a photodiode that can detect optical radiation at a broad range of wavelengths. The photodiode can be used as a detector of a non-invasive sensor, which can be used for measuring physiological parameters of a monitored patient. The photodiode can be part of an integrated semiconductor structure that generates a detector signal responsive to optical radiation at both visible and infrared wavelengths incident on the photodiode. The photodiode can include a layer that forms part of an external surface of the photodiode, which is disposed to receive the optical radiation incident on the photodiode and pass the optical radiation to one or more other layers of the photodiode.

  • Patent number: 9847749
    Abstract: Solar panels located on residential roofs can be unsightly in some cases. A swimming pool solar power generator can locate solar panels in or around the sides and/or bottoms of a swimming pool in a manner so as to create electricity from the sun without creating an eyesore. In an embodiment, a pool solar power generator includes a solar cell module disposed in a portion of a swimming pool. The solar cell module can include solar cells and be submerged under water held by the swimming pool. The solar cell module can convert sunlight incident on the solar cells to electricity and transmit the electricity for use at a location external to the swimming pool.

  • Patent number: 9368671
    Abstract: A method of fabricating on a semiconductor substrate bifacial tandem solar cells with semiconductor subcells having a lower bandgap than the substrate bandgap on one side of the substrate and with subcells having a higher bandgap than the substrate on the other including, first, growing a lower bandgap subcell on one substrate side that uses only the same periodic table group V material in the dislocation-reducing grading layers and bottom subcells as is present in the substrate and after the initial growth is complete and then flipping the substrate and growing the higher bandgap subcells on the opposite substrate side which can be of different group V material.

  • Publication number: 20130243021
    Abstract: A method of fabricating epitaxial structures including applying an etch stop to one side of a substrate and then growing at least one epitaxial layer on a first side of said substrate, flipping the substrate, growing a second etch stop and at least one epitaxial layer on a second side of the substrate, applying a carrier medium to the ultimate epitaxial layer on each side, dividing the substrate into two parts generally along an epitaxial plane to create separate epitaxial structures, removing any residual substrate and removing the etch stop.
