20140048117 | SOLAR ENERGY SYSTEMS USING EXTERNAL REFLECTORS - A concentrating photovoltaic system includes a condenser system and photovoltaic modules. The condenser system includes a quasi-Fresnel concave lens coated with an antireflection film and a reflector coated with a reflective film. The reflector is located between the quasi-Fresnel concave lens and the PV modules. A high refractive index optical resin is filled between the quasi-Fresnel concave lens and the photovoltaic modules. The quasi-Fresnel concave lens has a flat or hemispherical structure; the reflector can be placed horizontally, or at an angle to form a light condensing funnel. | 02-20-2014 |
20140045293 | FABRICATION OF INTERCONNECTED THIN-FILM CONCENTRATOR CELLS USING SHADOW MASKS - A method for fabricating thin film solar cells for a concentrated photovoltaic system uses three shadow masks. The first mask, used to deposit a back contact layer, has multiple horizontal and vertical lines defining columns and rows of cells, and multiple tabs each located in a cell along a center of a vertical border. The second mask, used to deposit a CIGS absorption layer, a window layer and a transparent contact layer, is similar to the first mask except the tabs are located along the opposite vertical border of the cells. The third mask, used to deposit a metal grid layer, has multiple bus bar openings and finger openings. Each bus bar opening is located along a horizontal center line of a cell and overlaps the second tab of a neighboring cell. The cells in a horizontal row are connected in series, forming a linear solar receiver. | 02-13-2014 |
20140044875 | IN-LINE DEPOSITION CHAMBER DESIGN FOR MULTI-STAGE PHYSICAL VAPOR DEPOSITION - An in-line multi-stage physical vapor deposition chamber is disclosed. The deposition chamber includes a cylindrical shaped main body, multiple dividers disposed within the main body and extending in radial directions to divide the interior space of the main body into multiple fan shaped zones, and a cylindrical shaped substrate holder disposed coaxially with the main body. The substrate holder is rotatable around a central axis, and individual substrates or a continuous flexible substrate is mounted on the substrate holder parallel to the central axis. Multiple metal source holders are disposed on the cylindrical sidewall of the main body in at least some of zones for mounting metal sources. Some zones are provided with heating mechanisms for heating the substrate. A load-lock chamber is connected to the main body for loading and unloading substrates into and from a first zone. | 02-13-2014 |
20140041708 | LOW-COST THIN-FILM CONCENTRATOR SOLAR CELLS - A low cost concentrating photovoltaic system includes a condenser system having refractive or reflective optics and a photovoltaic module having one or more thin film solar cells. The thin film solar cells may be a-Si, CdTe, Cu(InGa)Se | 02-13-2014 |
