Publication number: 20100180930Abstract: 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.Type: ApplicationFiled: February 19, 2008Publication date: July 22, 2010Inventors: Thomas Brezoczky, Chris M.

Publication number: 20100132795Abstract: An apparatus for converting light energy into electric energy has a concentrator with at least a first and second wall. The walls are made at least in part of a material that reflects light. The concentrator has an opening defined by the walls, and is operable to admit light energy into an interior portion of the apparatus. An elongated photovoltaic module is disposed between the walls.
