Patent number: 7122735Abstract: A method and apparatus that converts energy provided by a chemical reaction into energy for charging a quantum well device. The disclosed apparatus comprises a catalyst layer that catalyzes a chemical reaction and captures hot electrons and hot phonons generated by the chemical reaction, and an interface layer placed between the catalyst layer and a quantum well.

Patent number: 4447151Abstract: The method and device of the instant invention is a detector of pulsed laser radiation which utilizes the electromotive force generated by the plasma formed when such radiation is focused onto a surface (1). Measurements are made with a 10.6 .mu.m CO.sub.2 laser capable of producing peak intensities of 10.sup.13 W/cm.sup.2 when directed through a converging lens (2). Evacuated detector response to such laser intensity is 1 kV signal peak amplitude and subnanosecond risetimes into a 50.OMEGA. load (3). Detector performance is found to be greatly altered with the introduction of a background gas (4). For example, with one atmosphere of air, the detector produces prompt signals of the order of 1 V with subnanosecond response for pulse trains lasting 100 ns. With argon, krypton, or zenon at pressures of the order of 10 torr, the detector generates "trigger pulses" of about 250 V amplitude and 0.2 ns risetimes.Type: GrantFiled: June 18, 1981Date of Patent: May 8, 1984Assignee: The United States of America as represented by the Department of EnergyInventors: Edward J.

Patent number: 4410758Abstract: A photovoltaic cell and the method of manufacturing the same. The cell includes a substrate of, e.g., aluminum, having a layer of cesium fluoride-like material with the outer surface thereof containing a p+ boron doped outer layer. A substantially transparent electrically conductive coating is applied over the surface of said cesium fluoride-like material and appropriate electrical contacts are made to the conductive layer for protective purposes.Type: GrantFiled: April 27, 1982Date of Patent: October 18, 1983Assignee: Solar Voltaic, Inc.Inventor: Arthur J.

Patent number: 4365106Abstract: A very thin insulator having a dipole structure such as a dielectric material having ferroelectric, pyroelectric and or thermodielectric properties, is used as the insulator insulating an electrode of an electrode pair from a semiconductor body sandwiched between said electrode pair forming a MIS structure. Radiation and solar energy conversion systems based on establishment of an inversion layer by the thermally released bound charges of a polarizable dielectric layer or an electret and irradation of the semiconductor to separate the electron-hole pairs and subsequent collection of mobile carriers. Since there is no metalurgical junction, the generated carriers are not junction limited therefore the generated voltage could be higher than in an ordinary junction solar cell and could also be, an alternating current voltage which can be transformed or rectified.Type: GrantFiled: March 4, 1980Date of Patent: December 21, 1982Inventor: Charles F.

Patent number: 4264375Abstract: The reliability of a high intensity laser radiation surface ionization detector is increased by providing a target material for the high intensity laser radiation having a target material comprising a metal having a melting point below that of aluminum. The laser radiation detector has a linear response with respect to the incident laser radiation intensity when operated in the range 10.sup.6 -10.sup.7 W/cm.sup.2 and the distance between the target material and the walls of the evacuated chamber in which the target material is placed is less than the Debye length of the electrons in the plasma which was generated when the laser radiation strikes the target metal.Type: GrantFiled: September 17, 1979Date of Patent: April 28, 1981Assignee: Bell Telephone Laboratories, IncorporatedInventors: William T. Silfvast, Leo H. Szeto

Patent number: 4251679Abstract: Electromagnetic radiation is converted to usable power in the form of electrical current by means of a plurality of transducing cavities having a wall structure that is inclined inwardly to receive impinging radiation and includes potential barrier strips each having different conduction electron densities which are also different from the conduction electron density of the material constituting the wall structure of each cavity; each potential barrier strip extends from the mouth of the cavity to the base thereof and, at the mouth, is connected to a conductor having a preselected conduction electron density whereby radiation impinging on a cavity will induce current flow which will be rectified across the potential barriers; the cavities are connected in parallel so that current can be delivered to a load connected across the conductors.Type: GrantFiled: March 16, 1979Date of Patent: February 17, 1981Assignee: E-Cel CorporationInventor: Bryan J.
