| 20090056797 | Photovoltaic Thin-Film Solar Cell and Method Of Making The Same - A photovoltaic device having a front and back orientation and comprising: a crystalline substrate having a resistivity greater than about 0.01 ohm-cm; and an epitaxy thin-film layer in front of said substrate, said thin-film layer contacting said substrate in at least one region to define a p-n junction. | 03-05-2009 |
| 20090056805 | Photovoltaic Thin-Film Solar Cell and Method Of Making The Same - A photovoltaic device having a front and back orientation and comprising: a crystalline substrate having a resistivity greater than about 0.01 ohm-cm; and an epitaxy thin-film layer in front of said substrate, said thin-film layer contacting said substrate in at least one region to define a p-n junction. | 03-05-2009 |
| 20090314332 | HIGH EFFICIENCY SOLAR CELL - This invention relates to a high efficiency solar cell with a novel architecture. In one embodiment, the solar cell is comprised of a high energy gap cell stack and a dichroic mirror. The high energy gap cell stack is exposed to solar light before there is any splitting of the solar light into spectral components. Each cell in the high energy gap cell stack absorbs the light with photons of energy greater than or equal to its energy gap, i.e., the blue-green to ultraviolet portion of the solar light. Each cell in the high energy gap cell stack is transparent to and transmits light with photons of energy less than its energy gap. Spectral splitting is then performed by means of the dichroic mirror on the remaining light, i.e., the light transmitted by the high energy gap cell stack. | 12-24-2009 |
| 20090320903 | HIGH EFFICIENCY SOLAR CELL WITH A SILICON SCAVENGER CELL - This invention relates to an improved high efficiency solar cell with a “HEGC stack-dichroic mirror-MEGC stack” architecture or a “HEGC stack-dichroic mirror-MEGC stack-LEGC stack” architecture. The improvement comprises the addition of a silicon cell to act as a scavenger cell to absorb light that would otherwise not be absorbed and to convert that energy to electricity. The silicon cell is positioned adjacent to the cell with the smallest energy gap of the cells in the MEGC stack. | 12-31-2009 |
| 20100059107 | PHOTOVOLTAIC SOLAR CELL AND METHOD OF MAKING THE SAME - A front-surface-illuminated photovoltaic device, having a first semiconductor layer ( | 03-11-2010 |
| 20100078063 | HIGH EFFICIENCY HYBRID SOLAR CELL - This invention relates to a high efficiency hybrid solar cell preferably comprised of a static concentrator, a dichroic mirror, a first cell stack comprising two cells, the first cell being a GaInP cell and the second cell being a GaAs cell and a second cell stack comprising three cells, the first cell being a Si cell, the second cell being a GaInAsP cell and the third cell being a GaInAs cell. The dichroic mirror provides a separation of the solar light into two spectral components, one component of light with photons of energy≧E | 04-01-2010 |
| 20100170557 | High Efficiency Solar Cell With Surrounding Silicon Scavenger Cells - This invention relates to an improved high efficiency solar cell. The improvement comprises the addition of one or more silicon cells to surround at least a portion of the active region of the solar cell. Preferably, the silicon cells completely surround the active region of the solar cell. The silicon cells act as scavenger cells to absorb light that would otherwise not be absorbed by other components of the solar cell and to convert that energy to electricity. | 07-08-2010 |
