Abstract:
Under-gate field emission triode devices, and cathode assemblies for use therein, contain a charge dissipation layer. The charge dissipation layer may be located under or over the cathode electrode and/or electron field emitter.
Abstract:

Abstract:
A method for producing an array a thin-film solar cell with a cell level integrated bypass diode, the includes forming at least three series-connected solar cells; totally separating a bypass diode from a selected parent solar cell; connecting the semiconducting material of the first type of the photovoltaic junction layer of the bypass diode with the semiconducting material of the second type of any one chosen solar cell in the array; and connecting the semiconducting material of the second type of the photovoltaic junction layer of the bypass diode with the semiconducting material of the first type of any other chosen solar cell in the array so that the bypass diode is connected in parallel and in opposition to both the one chosen solar cell and the other chosen solar cell.
Abstract:
An array of at least three series-connected solar cells has a cell level integrated bypass diode formed by total separation from a selected parent cell. The material of the first type of the diode is connected to the material of the second type of any one chosen solar cell in the array. The material of the second type of the diode is connected with the material of the first type of the one chosen solar cell in the array so that the diode is connected in parallel and in opposition to the one chosen solar cell.
Abstract:
This invention relates to the electrochemical deposition of carbon nanotubes (“CNTs”) on a substrate using an electrochemical cell. A dispersion of a complex of CNTs and an anionic polymer is neutralized and thereby caused to deposit on the anode plate of the cell.
Abstract:
This invention provides a process for improving the field emission of an electron field emitter comprised of an acicular emitting substance such as acicular carbon, an acicular semiconductor, an acicular metal or a mixture thereof, comprising applying a force to the surface of the electron field emitter wherein the force results in the removal of a portion of the electron field emitter thereby forming a new surface of the electron field emitter.
Abstract:
This invention provides compositions that can be used as positive imageable photoresists. These compositions include positive imageable photopolymer systems and particulate materials. These compositions can be used in thick film and other processes to make films and patterned structures that are useful in producing electronic devices.
Abstract:
An array of series-connected solar cells is formed on a support layer with at least a two cells being adjacent and a third solar cell being either adjacent or separated from the second solar cell. A portion of the photovoltaic junction layer is separated from the first solar cell. The semiconducting material of the first type of the separated portion is electrically connected with the semiconducting material of the second type of the second solar cell through physical contact between the front electrode of the first cell and the back electrode of the second cell. The material of the second type of the separated portion of the junction layer is connected with the semiconducting material of the first type of the third cell to define a bypass diode that is in parallel and in opposition to the second and the third solar cells.
