  • Publication number: 20210297036
    Abstract: A photovoltaic (PV) module mounting system can have mounting clips that can be moved up and down a roof, and can allow the height of the mounting clips to be adjusted relative to the roof. At least a portion of the system can be made of a non-conductive material so that the system can be free of a grounding unit. The system can allow solar modules to be quickly installed, and can allow the solar modules to be removed quickly for repair or in the event of a fire.

  • Publication number: 20190326459
    Abstract: A method for encapsulating photovoltaic cells into single functional units is described. These units share the mechanical and electric properties of the encapsulation layers and allow for flexible module architecture to be implemented at the cell level. This enables cost reduction and improved performance of photovoltaic power generation.

  • Publication number: 20110027937
    Abstract: A template for growth of an anticipated semiconductor film has a deformation textured substrate. The template also has an intermediate epitaxial film coupled to the deformation textured substrate, the intermediate epitaxial film being chemically compatible and substantially lattice matched with the anticipated semiconductor film. A method of manufacturing a template for the growth of an anticipated semiconductor is also disclosed. A substrate is deformed to produce a textured surface. An intermediate epitaxial film, chemically compatible and substantially lattice matched with the anticipated semiconductor film, is deposited. A further disclosed photovoltaic device has a semiconductor layer, a deformation textured substrate, and an intermediate epitaxial film coupled to the deformation textured substrate. The intermediate epitaxial film is chemically compatible and substantially lattice matched with the semiconductor layer. The semiconductor layer is epitaxially grown on the intermediate epitaxial film.

  • Patent number: 7354490
    Abstract: High strength aluminum alloy powders, extrusions, and forgings are provided in which the aluminum alloys exhibit high strength at atmospheric temperatures and maintain high strength and ductility at extremely low temperatures. The alloy is produced by blending about 89 atomic % to 99 atomic % aluminum, 1 atomic % to 11 atomic % of a secondary metal selected from the group consisting of magnesium, lithium, silicon, titanium, zirconium, and combinations thereof, and up to about 10 atomic % of a tertiary metal selected from the group consisting of Be, Ca, Sr, Ba, Ra, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, W, and combinations thereof. The alloy is produced by nanostructure material synthesis, such as cryomilling, in the absence of refractory dispersoids. The synthesized alloy is then canned, degassed, consolidated, extruded, and optionally forged into a solid metallic component. Grain size within the alloy is less than 0.5 ?m, and alloys with grain size less than 0.

  • Patent number: 6974501
    Abstract: The invention relates to multi-layer articles and methods of making such articles. The methods include first conditioning the surface of an underlying layer, such as a buffer layer or a superconductor layer, then disposing a layer of material on the conditioned surface. The conditioned surface can be a high quality surface. Superconductor articles formed by these methods can exhibit relatively high critical current densities.
