20130240027 | MULTIJUNCTION HYBRID SOLAR CELL WITH PARALLEL CONNECTION AND NANOMATERIAL CHARGE COLLECTING INTERLAYERS - A tandem (or multijunction) hybrid photovoltaic device (PV) device comprised of multiple stacked single PVs connected in parallel with each other is described herein. Furthermore, nanomaterials are used as transparent charge collecting electrodes that allow both parallel connection via anode interlayer and also “inverted parallel” connection via cathode type interlayer of different types of solar cells. Carbon nanotube sheets are used as a convenient example for the charge collecting electrodes. The development of these alternative interconnecting layers simplifies the process and may be also used for combined organic PVs with traditional inorganic PVs and Dye Sensitized Solar Cells (DSSC). In addition, novel architectures are enabled that allow the parallel connection of the stacked PVs into monolithic multi-junction PV tandems. This new monolithic parallel connection architecture enables enhanced absorption of the solar spectrum and results in increased power conversions efficiency. Moreover, architectures where cells are stacked monolithically using a series connection can be coupled with cells to create mixed series and parallel connected tandem cells. | 09-19-2013 |
20130240847 | MONOLITHIC PARALLEL MULTIJUNCTION OLED WITH INDEPENDENT TUNABLE COLOR EMISSION - A tandem organic light emitting diode (OLED) device comprised of multiple stacked single OLEDs electrically connected in parallel via transparent interlayer is recited herein. Transparent interlayers are coated by charge injection layers in order to enhance the charge injection efficiency and decrease the operation voltage. Transparent nanomaterials, such as carbon nanotube sheets (or graphene, graphene ribbons and similar conductive transparent nano-carbon forms) are used as Interlayers or outer electrodes. Furthermore, functionalization of carbon nanotubes inter layers by n-doping (or p-doping) converts them into common cathode (or common anode), further decreasing operation voltage of tandem. The development of these alternative interconnecting layers comprised of nanomaterials simplifies the process and may be combined with traditional OLED devices. In addition, novel architectures are enabled that allow the parallel connection of the stacked OLEDs into monolithic multi-junction OLED tandems. | 09-19-2013 |

20150040888 | INTEGRATION OF PHASE CHANGE MATERIALS INSIDE EVACUATED TUBE SOLAR COLLECTOR FOR STORAGE AND TRANSFER OF THERMAL ENERGY - An objective of the invention is to design and develop an effective method to collect and store heat in a solar collector for delayed release. An embodiment of the invention is directed to an evacuated tube collector, where PCM is placed directly inside the void space of the collector tube, next to the heat pipe. The heat pipe is located with phase change material (PCM) in such a way that its thermal connection with the heat pipe can be switched “ON” to start heat transfer from PCM or “OFF” to keep latent heat stored in PCM for delayed usage. In additional, flow of heat exchange fluid through the manifold can enable release of stored heat of PCM to storage tank. Delayed release of accumulated heat in PCM enables added functionality of on-demand operation of SWH. | 02-12-2015 |
