| 20080196759 | Photovoltaic assembly with elongated photovoltaic devices and integrated involute-based reflectors - A photovoltaic assembly has elongated photovoltaic modules. The photovoltaic modules each have a substrate with a photovoltaic material disposed on the substrate. Each respective photovoltaic module lies in the concave structure of a corresponding concentrator assembly. The concentrator assemblies have surfaces made with reflective material that form such concave structures. The concentrator assemblies each transmit light to their corresponding photovoltaic module. The surfaces of each concentrator assembly are shaped at least in part as an involute of the surface of their corresponding photovoltaic modules, and do not exceed the height of the their corresponding module. A frame is provided having a first support and a second support, where the modules extend between the supports. The concentrator is mechanically attached to the frame. A substantial portion of light striking the concentrator is ultimately redirected to the modules without associated tracking and/or control devices. | 08-21-2008 |

| 20090120486 | Bifacial Solar Cell Array - First and second solar panels are mounted in an operative position. Each panel includes an upward-facing photovoltaic surface and a downward-facing photovoltaic surface that are configured to photovoltaically generate electricity from light. The downward-facing photovoltaic surface is spaced above a reflective surface. The first and second panels are spaced apart in a first direction by a spacing distance that is about 25% to about 100% of the width of the first panel in the first direction. Some downwardly-directed light rays can strike the upward-facing photovoltaic surfaces of the panels. Other downwardly-directed light rays can pass between the first and second panels and be reflected upward by the reflective surface to strike the downward-facing photovoltaic surfaces of the panels. | 05-14-2009 |
