20130068293 | SUBSTRATE GEOMETRY FOR THREE DIMENSIONAL PHOTOVOLTAICS FABRICATION - A thin film photovoltaic device with back contacts is disclosed. The thin film photovoltaic device may comprise 1) a first contact disposed in a first layer and having an upper surface and a lower surface; 2) a first semiconductor disposed in a second layer and having a lower surface disposed on the upper surface of the first contact; 3) an insulator or second semiconductor disposed in a third layer and on an upper surface of the first semiconductor; 4) a second contact disposed in a fourth layer and on the insulator or second semiconductor; and 5) an absorber disposed in a fifth layer and about the second contact. The absorber may comprise a p-type or a n-type semiconductor and the first semiconductor may comprise the other of the p-type and n-type semiconductor. The second contact may be patterned. | 03-21-2013 |

20120021248 | SYNTHESIS OF NANOPEAPODS BY GALVANIC DISPLACEMENT OF SEGMENTED NANOWIRES - A method for fabricating nanostructures, which includes the steps of forming a multi-segmented nanowire; and performing a galvanic displacement reaction on the multi-segmented nanowire. The method utilizes template directed electrodeposition to fabricate nanowires with alternating layers of sacrificial/noble metal, enabling a new level of control over particle spacing, aspect ratio, and composition. Moreover, by exploiting the redox potential dependent reaction of galvanic displacement, nanopeapod materials can be extended (semiconductor/metal, p-type/n-type, metal/metal, ferromagnetic/nonmagnetic, etc.) beyond the fundamental metal/metal-oxide nanopeapods synthesized by high temperature techniques. In accordance with an exemplary embodiment. Co/Au and Ni/Au multisegmented nanowires were used to create Te/Au nanopeapods by galvanic displacement, producing Te nanotubes and nanowires with embedded Au particles, respectively. | 01-26-2012 |
