  • Patent number: 7321095
    Abstract: A solar generator panel includes at least one reflector for reflecting solar radiation onto at least one photovoltaic cell. The reflector takes the form of a flexible material blade, a first end of which is fixed to the panel and a second end of which remains free. The material has mechanical properties such that, in a first position, in the absence of vertical pressure, it maintains itself erect so that its free end points to outer space, thereby defining an upper face that faces outer space and an opposite lower face that faces the panel, and, in a second position, in response to vertical pressure, it orients its upper face toward the plane of the panel. One particular application is to high-power solar panels for satellites.

  • Patent number: 7281381
    Abstract: A mechanical thermo-voltaic solar power system (MeTSoPoS) that uses a mechanical generator, instead of the photovoltaic panel commonly in use today, is disclosed. The system is comprised of three major subsystems: (1) a light collector array, (2) a mechanical thermo-voltaic generator, and (3) a storage and retrieval system. At the center of the system is the light collection array comprised of solar collector elements. These collector elements are connected to optical conduits (fiber optic cables) that carry the light energy to a mechanical generator. An automatic aiming system is used to align the collector elements directly at a light source for maximum light output. Each light collector element is comprised of a set of lenses that focus a larger area of light down to a point small enough to inject into an optical conduit. The optical conduit is then used to carry the light from each collector element to the generator.

  • Patent number: RE39967
    Abstract: A solid state photovoltaic device is formed on a substrate and includes a photoactive channel layer interposed between a pair of electrodes. The photoactive channel layer includes a first material which absorbs light and operates as a hole carrier. Within the first material are nanoparticles of a second material which operate as electron carriers. The nanoparticles are distributed within the photoactive channel layer such that, predominantly, the charge path between the two electrodes at any given location includes only a single nanocrystal. Because a majority of electrons are channeled to the electrodes via single nanocrystal conductive paths, the resulting architecture is referred to as a channel architecture.
