Photovoltaic solar cell

Patent Nielson, Gregory N. ; Gupta, Vipin P. ; Okandan, Murat ; Watts, Michael R.

A photovoltaic solar concentrator is disclosed with one or more transverse-junction solar cells (also termed point contact solar cells) and a lens located above each solar cell to concentrate sunlight onto the solar cell to generate electricity. Piezoelectric actuators tilt or translate each lens to track the sun using a feedback-control circuit which senses the electricity generated by one or more of the solar cells. The piezoelectric actuators can be coupled through a displacement-multiplier linkage to provide an increased range of movement of each lens. Each lens in the solar concentrator can be supported on a frame (also termed amore »« less

Moldable photovoltaic solar cell module

Patent Nelson, Jeffrey S. ; Hibbs, Michael ; Nielson, Gregory N. ; Okandan, Murat ; Cruz-Campa, Jose Luis ; Resnick, Paul J. ; Sanchez, Carlos Anthony ; Gupta, Vipin P. ; Clews, Peggy J.

A moldable photovoltaic module is provided. The module includes a flexible polymeric flex-circuit substrate having an electrically conductive printed wiring pattern and solder pads defined on it. Small photovoltaic cells are affixed to the flex-circuit substrate by back-surface contacts in electrical contact with the solder pads. At least one thermoformable polymeric film is joined to the flex-circuit substrate. Each said solder pad comprises a solder composition that, after an initial melt, has a melting point that lies above at least a portion of the temperature range for thermoforming the polymeric film.

A single-stack, solar power receiver comprising both a thermal absorber layer and a photovoltaic cell layer. The stack includes an aerogel layer, that is optically transparent and thermally insulating ("OTTI"); a spectrally selective high thermal conductivity ("SSTC") thermal absorber layer; a bottom OTTI layer; and a PV cell layer. The SSTC layer includes a set of fins that substantially blocks solar radiation absorption in the band where PV cells are most sensitive. Photons with energies above or below this band block range are absorbed by the fins and the absorbed heat is conducted to pipes in the fin structure carryingmore »« less
