    摘要: 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.

    摘要: Devices that include one or more functional semiconductor elements that are immersed in static electric fields (E-fields). In one embodiment, one or more electrets are placed proximate the one or more organic, inorganic, or hybrid semiconductor elements so that the static charge(s) of the electret(s) participate in creating the static E-field(s) that influences the semiconductor element(s). An externally applied electric field can be used, for example, to enhance charge-carrier mobility in the semiconductor element and/or to vary the width of the depletion region in the semiconductor material.

    摘要: Titania is a semiconductor and photocatalyst that is also chemically inert. With its bandgap of 3.2 and greater, to activate the photocatalytic property of titania requires light of about 390 nm wavelength, which is in the ultra-violet, where sunlight is very low in intensity. A method and devices are disclosed wherein stress is induced and managed in a thin film of titania in order to shift and lower the bandgap energy into the longer wavelengths that are more abundant in sunlight. Applications of this stress-induced bandgap- shifted titania photocatalytic surface include photoelectrolysis for production of hydrogen gas from water, photovoltaics for production of electricity, and photocatalysis for detoxification and disinfection.

    摘要: A thin silicon solar cell is described. Specifically, the solar cell may be fabricated from a crystalline silicon wafer having a thickness of approximately 50 micrometers to 500 micrometers. The solar cell comprises a first region having a p-n homojunction, a second region that creates heterojunction surface passivation, and a third region that creates heterojunction surface passivation. Amorphous silicon layers are deposited on both sides of the silicon wafer at temperatures below approximately 400 degrees Celsius to reduce the loss of passivation properties of the amorphous silicon. A final layer of transparent conductive oxide is formed on both sides at approximately 165 degrees Celsius. Metal contacts are applied to the transparent conductive oxide. The low temperatures and very thin material layers used to fabricate the outer layers of used to fabricate the outer layers of the solar cell protect the thin wafer from excessive stress that may lead to deforming the wafer.
