20090114265 | Solar Concentrator - The present invention is an improved solar concentrator array utilizing a monolithic array of primary mirrors with a metal layer deposited on its backside for electrical purposes and for dissipating heat. The array of primary mirrors may be formed by glass slumping. The size of the primary mirrors is chosen to accommodate design aspects related to performance, manufacturing processes, cost, and thermal management. An electrical package, which in one embodiment is a molded leadframe, provides the electrical circuitry between a solar cell and the metal layer. The electrical package may be configured with features such as an aperture or side edges to enhance manufacturability of the solar concentrator array. An array of secondary mirrors may be integrally formed with a front panel of the solar concentrator. | 05-07-2009 |
20090120499 | SYSTEMS TO RETAIN AN OPTICAL ELEMENT ON A SOLAR CELL - A system may include a solar cell, a support defining an opening over the solar cell and comprising a retention feature, and an optical element disposed within the opening. The optical element may include a location feature engaged with the retention feature of the support. In some aspects, the optical element includes an upper surface to receive concentrated light and a lower surface through which light passes to the solar cell, and the location feature is disposed between the upper surface and the lower surface. The retention feature may be a lip defining the opening over the solar cell, and/or the location feature may consist of a notch defined by an edge of the optical element. | 05-14-2009 |
20090120500 | SOLAR CELL PACKAGE FOR SOLAR CONCENTRATOR - A system may include a substrate, and a solar cell including a top side and a bottom side, the top side having an active area and the bottom side coupled to the substrate. A frame may be coupled to the substrate, the frame defining an upper opening above the active area and a lower opening above the active area and between the active area and the upper opening. The lower opening may be smaller than the upper opening in at least one dimension, and an optical element may be disposed within the upper opening. | 05-14-2009 |
20090159125 | SOLAR CELL PACKAGE FOR SOLAR CONCENTRATOR - An apparatus may include an integrated circuit package substrate comprising a first surface and a second surface, a solar cell coupled to the first surface of the integrated circuit package substrate, and a light-transmissive element coupled to the second surface of the integrated circuit package substrate. The integrated circuit package substrate and the light-transmissive element form a hermetic seal or a semi-hermetic seal around the solar cell. | 06-25-2009 |
20090159128 | LEADFRAME RECEIVER PACKAGE FOR SOLAR CONCENTRATOR - A system includes a leadframe comprising a first conductive element, a solar cell electrically coupled to the first conductive element and comprising an active area, and mold compound disposed on the leadframe and the solar cell. The mold compound defines a first aperture over at least a portion of the active area and a second aperture over at least a portion of the first conductive element. | 06-25-2009 |
20090241940 | SOLAR THERMAL COLLECTOR MANIFOLD - A solar thermal energy collector manifold is provided. The manifold is connected to solar collector tubes for collecting solar energy.
