20100326497 | HIGHLY EFFICIENT TANDEM POLYMER PHOTOVOLTAIC CELLS - A tandem polymer photovoltaic device includes a first bulk hetero-junction polymer semiconductor layer, a second bulk hetero-junction polymer semiconductor layer spaced apart from the first bulk hetero-junction polymer semiconductor layer, and a metal-semiconductor layer between and in contact with the first and second bulk hetero junction polymer semiconductor layers. The first and second bulk hetero-junction polymer semiconductor layers have complementary photon absorption spectra. | 12-30-2010 |
20110008926 | SOLAR CELL WITH CONDUCTIVE MATERIAL EMBEDDED SUBSTRATE - Conductive material grids or lines embedded or partially embedded in a transparent substrate of a solar cell. The grids or lines can have a higher conductivity than the anode or they can have the same conductivity. The grids or lines increase the volume of the anode and, thus decrease sheet resistance of the same. | 01-13-2011 |
20110108856 | ORGANIC LIGHT EMITTING DIODE AND ORGANIC SOLAR CELL STACK - This disclosure relates to an organic solar cell and an organic light emitting diode stack. The stack comprises a solar cell portion having a substrate, an electrode, an active layer, and a second electrode. The stack also comprises a light emitting diode portion having a substrate, an electrode, an active layer, and a second electrode. The solar cell portion is laminated to the light emitting diode portion to form a stack. In a variation, the stack comprises a solar cell portion that includes a substrate, an electrode and an active layer. In this variation, there is a connection portion that includes a second substrate, having a second electrode on one side and a third electrode on the other side of the second substrate. Also in this variation, there is also a light emitting diode portion, which includes a third substrate, an electrode on the third substrate and a second active layer. The solar cell portion is laminated to the connection portion and the connection portion is laminated to the light emitting diode portion to form a stack. | 05-12-2011 |
20150344495 | PROCESS OF MAKING DIFLUOROTHIENOTHIOPHENE BASED CONJUGATED POLYMERS - A method of producing a monomer wherein the method begins by dissolving 3-fluoro-4,6 dihydrothieno[3,4-b]thiophene in a solvent to create a solution. An initiator is then added to the solution to produce an initiated solution. This is followed by adding a fluorinated chemical to the initiated solution to produce 2,3-difluoro-4,6-dihydrothieno[3,4-b]thiophene. 2,3-difluoro-4,6-dihydrothieno[3,4-b]thiophene is then oxidized with an oxidant to produce 2,3-difluorothieno[3,4-b]thiophene. 2,3-difluorothieno[3,4-b]thiophene is then bromoated to produce 4,6-dibromo-2,3-difluorothieno[2,3-c]thiophene. The final step involves debrominating 4,6-dibromo-2,3-difluorothieno[2,3-c]thiophene and adding an aryl group to produce the monomer | 12-03-2015 |
