20100326492 | Photovoltaic Cell Support Structure Assembly - A plurality of CPV cells are mounted on a common ALOX™ plate. A copper interconnection layer is deposited over an insulating aluminum oxide surface of the ALOX™ plate. The interconnection layer connects all the CPV cells in series, so no wires are needed. In one embodiment, each CPV cell is mounted on a ceramic submount or an ALOX™ submount having an electrically insulating aluminum oxide layer formed in its bottom surface. Vias through the submount couple the cell electrodes to the copper interconnection pattern on the ALOX™ plate. The ALOX™ plate may be the heat sink or may be bolted or soldered to a separate heat sink. In one embodiment, edges of the ALOX™ plate are bent upwards, and side panels are affixed to the ALOX™ plate to create a box that supports a Fresnel lens that directs sunlight to each of the cells (e.g. nine) mounted on the ALOX™ plate. | 12-30-2010 |
20100319773 | Optics for Concentrated Photovoltaic Cell - A concentrated photovoltaic (CPV) module includes a CPV cell mounted on a support surface. A primary optical element (POE) is a square Fresnel lens fixed in position over the CPV cell. A secondary optical element (SOE) is optically coupled to the cell for providing uniform light over the surface of the cell. The SOE has a square, sloping top portion and a truncated pyramid shaped bottom portion that tapers toward the cell. The top portion is formed of angled flat square rings that refract light entering the top portion from the POE. The bottom portion mixes the light using TIR. The SOE has an angled middle portion, and an integral support structure having one end attached to the middle portion surrounds the bottom portion and is attached to the cell support surface so there is little mechanical stress on the cell. | 12-23-2010 |
