  • Patent number: 9691554
    Abstract: A method of forming an ordered nanorods array in a confined space is used to form a high surface area device where an ensemble of parallel trenches has micrometer dimensions for the width and depth of the trenches, which are decorated with crystalline nanowires radiating from the sidewalls and bases of the trenches. The high surface area device is formed by depositing a conformal crystalline seed coating in the trenches, forming microchannels from these trenches by placing a barrier layer on the open surface of the trenches, contacting the conformal coating with a crystal precursor solution that is caused to flow through the microchannels. In an embodiment, a very high surface area electrode is constructed with ZnO nanowires radiating from the sidewalls and base of trenches formed on a silicon substrate. The device can be a dye-sensitized solar cell.

  • Publication number: 20130092237
    Abstract: The invention provides a bio-photovoltaic device, in which a photoelectric center, exemplified by a biological photosynthetic reaction center (RC), is dispersed and mobile in a medium, such as an aqueous solution. The charges generated by the illuminated RC are transferred to electrodes via one or more mediators. In selected embodiments, the difference between the reaction rates of two types of mediator at the electrode surfaces, in conjunction with other charge transfer reaction equilibria, determines the direction of the photocurrent in the device. In an exemplified embodiment, the magnitude of the photocurrent is proportional to the incident light intensity, and the current increases nonlinearly with an increase in the RC concentration in the medium.

  • Patent number: 7649217
    Abstract: An active electronic device has drain and source electrodes that make ohmic conduct with a layer of a semiconductor. The semiconductor layer may be a thin layer of an organic or amorphous semiconductor. The drain and source electrodes are on a first face of the layer of semiconductor at locations that are spaced apart on either side of a channel. The device has a gate electrode on a second face of the layer of semiconductor adjacent to the channel. The gate electrode makes a Schottky contact with the semiconductor to produce a depletion region in the channel. The gate electrode may encapsulate the channel so that the channel is protected from contact with oxygen, water molecules or other materials in the environment. In some embodiments, the device has an additional gate electrode separated from the semiconductor layer by an insulating layer. Such embodiments combine features of OFETs and MESFETs.
