Abstract: A double-sided photovoltaic package with an incident photovoltaic cell and a reflective photovoltaic cell. Both photovoltaic cells have a corresponding absorbing surface for absorbing solar radiation. The incident photovoltaic cell and the reflective photovoltaic cell are arranged so that when the absorbing surface of the incident photovoltaic cell is located to receive incident non-reflected solar radiation the absorbing surface of the reflective photovoltaic cell is located to receive reflected solar radiation. The structure of the incident photovoltaic cell is adapted to convert non-reflected light to electrical energy and the structure of the reflective photovoltaic cell is adapted to convert reflected light to electrical energy. Additionally, in the preferred embodiment, the incident photovoltaic cell and the reflective photovoltaic cell both comprise inverted metamorphic multijunction photovoltaic cells.

Abstract: A bag having a tamper evident closure and methods of forming the same are provided. The bag has a tube body with a front wall and a back wall positioned between a first end and a second end. A back flap extension member connects to and extends outwardly from the second end of the back wall. A primer material is positioned on the back flap extension member and an adhesive material is placed on the back flap extension member that folds over to overlie and contact the primer material. The back flap extension member adheres to the front flap extension member and portions of the front wall to close the second end. When the back flap extension member liftingly separates from the front wall, at least one of the back flap extension member and the front wall tears indicating evidence of tampering.

Abstract: A method of producing a nonwoven fabric comprising spinning a set of bicomponent fibers which include an external fiber component and an internal fiber component. The external fiber enwraps said internal fiber and has a higher elongation to break value than the internal fiber and a lower melting temperature than the internal fiber component. The set of bicomponent fibers are positioned onto a web and thermally bonded to produce a nonwoven fabric.

Abstract: A method of forming a multijunction solar cell comprising an upper subcell, a middle subcell, and a lower subcell by providing a first substrate for the epitaxial growth of semiconductor material; forming a first solar subcell on said substrate having a first band gap; forming a second solar subcell over said first subcell having a second band gap smaller than said first band gap; forming a grading interlayer over said second subcell having a third band gap larger than said second band gap; forming a third solar subcell having a fourth band gap smaller than said second band gap such that said third subcell is lattice mismatched with respect to said second subcell; and etching a via from the top of the third subcell to the substrate to enable both anode and cathode contacts to be placed on the backside of the solar cell.

Abstract: Apparatus and Method for Optimizing the Efficiency of Germanium Junctions in Multi-Junction Solar Cells. In a preferred embodiment, an indium gallium phosphide (InGaP) nucleation layer is disposed between the germanium (Ge) substrate and the overlying dual-junction epilayers for controlling the diffusion depth of the n-doping in the germanium junction. Specifically, by acting as a diffusion barrier to arsenic (As) contained in the overlying epilayers and as a source of n-type dopant for forming the germanium junction, the nucleation layer enables the growth time and temperature in the epilayer device process to be minimized without compromising the integrity of the dual-junction epilayer structure. This in turn allows the arsenic diffusion into the germanium substrate to be optimally controlled by varying the thickness of the nucleation layer.

Abstract: The syringe includes a barrel, a plunger, and an adapter for mounting the needle in the distal end of the barrel. The adapter includes a protrusion projecting away from the needle end and into the barrel defining an annular space between the barrel and the protrusion. The plunger and protrusion have complementary surfaces whereby the plunger may grip the adapter for removal of the adapter into the interior of the barrel after use. These complementary surfaces afford initial resistance to further axial movement of the plunger toward the adapter, signalling the user that further axial pressure will permanently lock the plunger and adapter to one another whereby, upon application of full axial pressure on the plunger, the complementary surfaces of the plunger and adapter permanently lock to one another to enable joint unitary movement of the plunger and adapter together with the needle carried by the adapter into the barrel.
