  • Patent number: 10164135
    Abstract: Certain example embodiments of this invention relate to the use of graphene as a transparent conductive coating (TCC). In certain example embodiments, graphene thin films grown on large areas hetero-epitaxially, e.g., on a catalyst thin film, from a hydrocarbon gas (such as, for example, C2H2, CH4, or the like). The graphene thin films of certain example embodiments may be doped or undoped. In certain example embodiments, graphene thin films, once formed, may be lifted off of their carrier substrates and transferred to receiving substrates, e.g., for inclusion in an intermediate or final product. Graphene grown, lifted, and transferred in this way may exhibit low sheet resistances (e.g., less than 150 ohms/square and lower when doped) and high transmission values (e.g., at least in the visible and infrared spectra).

  • Patent number: 9171982
    Abstract: Provided are novel building integrable photovoltaic (BIPV) modules having integrated jumpers for interconnecting similar modules in adjacent rows. An integrated jumper is provided on a back side of the photovoltaic portion of the module and includes at least two interconnected jumper contact points. The module also has two connectors provided on the front side of its flap portion. Each connector has at least one connector contact point connected to one or more photovoltaic cells of the module. When a module is positioned over flap portions of two other modules previously installed in an adjacent row, the two jumper contact points on the back side of this new module make electrical connections to the two connector contact points on the front side of the installed modules. In turn, these connections interconnect the photovoltaic cells of the two modules without any need for additional connectors or operations.

  • Patent number: 9059352
    Abstract: A solar energy concentrating system with high light collection efficiency includes a light concentrating unit, a light homogenizing unit and photovoltaic modules. The light concentrating unit includes a parabolic reflector and an ellipsoidal reflector which are coaxial and confocal. The light homogenizing unit includes an infrared filter and a hollow spherical reflector with a hole in its surface. When the system is under illumination, light is concentrated by the light concentrating unit through the hole in the spherical reflector surface and reflected by the inner surface of the spherical reflector onto the photovoltaic modules. The infrared filter covers the hole in the spherical reflector surface and reduces the heat in the photovoltaic modules under concentrated light. The combination of the parabolic reflector and the ellipsoidal reflector obtain highly concentrated light, and the hollow spherical reflector ensures light uniformity on the photovoltaic modules and light utilization efficiency.

  • Patent number: 8586854
    Abstract: A thermoelectric conversion element is configured to have two types of conductors with different Seebeck coefficients physically connected alternately with an electrode via one or more electrical resistance layers formed by electrical resistor having electrical resistance rate of 1×10?3 ?cm or more. This arrangement enables charges to be generated by the difference of temperature in both ends of the element and to be densely stored in the electrical resistance layers formed by electrical resistor. Moreover, it is thought that thermal energy equivalent to the difference of temperature is input into the electrical resistance layers and that electromotive force increases as a result of an increase of output voltage.

  • Patent number: 8492645
    Abstract: A transportable, self-contained, solar power system comprised of a plurality of individual solar power arrays, each array being contained within a transportable frame. Each array is folded into a frame during transportation. Upon reaching a desired location, the frame is positioned at a desired location. The frame then acts as a base while its solar power array is activated and deployed. The array has the capability of tracking the position of the sun during deployment. Each frame has a global positioning system (GPS) and a controller containing a chart of sun locations for a given location. The controller positions a frame's solar array to maximize the array's exposure to the sun. Each frame has a battery system, enabling a frame's solar array to self-start after a period of darkness.
