  • Patent number: 9831706
    Abstract: The present invention is directed to techniques and apparatus for generating power using multi-spectrum energy. An apparatus includes an electrical device and a power source, the power source comprising a multi-spectrum power generation system in electrical communication with the mobile electrical device, the multi-spectrum power generation system including a photovoltaic electrical power generator, and a microelectromechanical power generator; a primary power storage system in electrical communication with the electrical device; and a controller system in data communication with the multi-spectrum energy power generator systems to regulate electrical communication between the power storage system and the power generation system. In an alternative embodiment, the multi-spectrum power generation system may further a thermoelectric power generator.

  • Patent number: 9525304
    Abstract: The present invention is directed to a charging system for charging an electrical device coupled to a photovoltaic electrical power generator and one or more of a microelectromechanical power generator and a thermoelectric power generator. The system includes a source of optical energy and a base portion. The base portion has a surface, and the source is disposed to impinge optical energy toward the surface. One or more of a heat source and an oscillator and is included in the base portion. The oscillator is connected to cause vibration of the surface, and the heat source is in thermal communication with the surface. The electrical device is disposed upon the surface to sense the optical energy and one or more of the vibration and the thermal energy. The charging station can be employed to rapidly charge an electrical device, such as a mobile electric device that facilitates multi-spectrum power generation.

  • Publication number: 20130045560
    Abstract: The present invention is directed to techniques for fabricating solar cells that feature annealing of a substrate and subsequent formation of a combination passivation and antireflective layer in superimposition with a p-n junction formed on the substrate by introductions of impurities. It was determined that the time and cost for manufacture may be reduced by annealing the substrate before formation of the combination layer and maintaining the temperature proximate to the annealing temperature. To that end, upon completion of the anneal process the temperature of the substrate is maintained within an acceptable temperature range to reduce the time required for the substrate to reach temperature for formation of the combination layer. The combination layer is then formed without undue delay using plasma deposition processes.
