A p-type semiconductor hole-transport material (HTM) layer is formed adjacent to the semiconductor absorber layer, and a metal electrode is formed. adjacent to the HTM layer. In one aspect, the HTM layer is an inorganic material such as a p-type metal oxide. Some explicit examples of HTM materials include stoichiometric and non-stoichiometric molybdenum (VI) oxide, stoichiometric and non-stoichiometric vanadium (V) oxide, stoichiometric and non-stoichiometric nickel (II) oxide, and stoichiometric and non-stoichiometric copper (I) oxide. Also provide are planar solar cell devices. | 01-07-2016 |
| 20160099367 | Hybrid Trough Solar Power System using Photovoltaic Two-Stage Light Concentration - A solar power method is provided using two-stage light concentration to drive concentrating photovoltaic conversion in conjunction with thermal collection. The method concentrates light rays received in a plurality of transverse planes towards a primary linear focus in an axial plane, which is orthogonal to the transverse planes. T hand wavelengths of light are transmitted to the primary linear focus. R hand wavelengths of light are reflected towards a secondary linear focus in the axial plane, which is parallel to the primary linear focus. The light received at the primary linear focus is translated into thermal energy. The light received at the secondary linear focus is focused by optical elements along a plurality of tertiary linear foci, which are orthogonal to the axial plane. The focused light in each tertiary primary focus is focused into a plurality of receiving areas, and translated into electrical energy. | 04-07-2016 |
| 20160099674 | Flat Panel Photovoltaic System - A flat panel photovoltaic (PV) system is provided formed from a first sheet with rows of concentrated III-V photovoltaic (CPV) solar cells. An overlying second sheet is made up of rows of waveguides, where each waveguide is coupled to a corresponding CPV solar cell. A third sheet includes overlying one-piece linear lenses, each having a focal line coupled to the waveguides in a corresponding row. Optionally, a fourth sheet underlies the first sheet, which is a 1-sun solar panel including a plurality of silicon PV cells. In one variation adjacent rows of waveguides couple to the same row of CPV cells. In another variation, each waveguide in a row is optically coupled to waveguides in an adjacent row, which adjacent waveguides are then coupled to a corresponding row of CPV cells. A lens overlies each row of waveguides, with a focal line coupled to each waveguide in that row. | 04-07-2016 |
| 20160099675 | Solar Concentrator with Asymmetric Tracking-Integrated Optics - A method is provided for using asymmetrically focused photovoltaic conversion in a hybrid parabolic trough solar power system. Light rays received in a plurality of transverse planes are concentrated towards a primary linear focus in an axial plane, orthogonal to the transverse planes. T band wavelengths of light are transmitted to the primary linear focus, while R band wavelengths of light are reflected towards a secondary linear focus in the axial plane. The light received at the primary linear focus is translated into thermal energy. The light received at the secondary linear focus is asymmetrically focused along a plurality of tertiary linear foci, orthogonal to the axial plane. The focused light in each tertiary linear focus is concentrated into a plurality of receiving areas and translated into electrical energy. Asymmetrical optical elements are used having an optical input interfaces elongated along rotatable axes, orthogonal to the axial plane. | 04-07-2016 |
| 20160111705 | Metal-Air Battery with Expandable Anode - An air cathode battery is provided with a slurry anode. An anode cavity is interposed between the air cathode interior surfaces, with an anode compartment occupying the anode cavity. The anode compartment has a first wall and a second wall, one or both capable of movement. An anode current collector pouch has walls adjacent to interior surfaces of the anode compartment. A zinc slurry occupies an expandable region in the anode compartment between the anode current collector pouch and the anode compartment wall interior surfaces. The anode current collector pouch first wall and second wall contract towards each other in response to expansion in the volume of zinc slurry. In one aspect, the anode compartment first and second walls expand away from each other in response to expansion in the volume of zinc oxide. A replenishable electrolyte source may be used to provide electrolyte to the anode cavity. | 04-21-2016 |
