20110100412 | METHOD OF MANUFACTURING PHOTOVOLTAIC MODULES - A photovoltaic module and a method of manufacturing such a module in which metal is deposited in a pattern on the front side of a semiconductor wafer which acts as an electrode. Photovoltaic cells manufactured using a semiconductor wafer typically have a P type semiconductor region and an N type semiconductor region. The metal on the front side of each of the photovoltaic cells forms an electrical connection to the doped layer of the semiconductor wafer on its front side. | 05-05-2011 |
20110100413 | REGENERATION METHOD FOR RESTORING PHOTOVOLTAIC CELL EFFICIENCY - An apparatus, system, and method are disclosed for restoring efficiency of a photovoltaic cell. An illumination module illuminates photovoltaic cells so the cells receive a time integrated irradiance equivalent to at least 5 hours of solar illumination. After illumination, an annealing module anneals the photovoltaic cells at a temperature above 90 degrees Celsius for a minimum of 10 minutes. In one embodiment, the illumination module illuminates the photovoltaic cells for a time integrated irradiance equivalent to at least 20 hours of solar illumination. In another embodiment, the illumination module illuminates the photovoltaic cells for a time integrated irradiance equivalent to at least 16 hours of solar illumination while being heated to at least 50 degrees Celsius. In another embodiment, a solar concentrator irradiates the photovoltaic cells in sunlight for at least 10 hours and increases the irradiance of solar illumination on the cells by a factor of 2 to 5. | 05-05-2011 |
20110100420 | PHOTOVOLTAIC MODULE WITH A CONTROLLABLE INFRARED PROTECTION LAYER - An apparatus, system, and method are disclosed for a photovoltaic module, the photovoltaic module comprising a plurality of photovoltaic cells, a controllable infrared protection layer, and a protection switching means. The controllable infrared protection layer is for reducing the infrared radiation absorbed by the photovoltaic module, where the controllable infrared protection layer has a first state and a second state. When the infrared protection layer is in the first state the transmission of infrared radiation to the photovoltaic cells is higher than when the infrared protection layer is in the second state. The protection switching means is for switching the controllable infrared protection layer between the first state and the second state. | 05-05-2011 |
20120160295 | SOLAR CELL CLASSIFICATION METHOD - A method for characterizing the electronic properties of a solar cell to be used in a photovoltaic module comprises the steps of performing a room temperature IV curve measurement of the solar cell and classifying the solar cell based on this IV curve measurement. In order to take stress-related effects into account, the solar cells are reclassified depending on the result of an additional measurement conducted on the solar cells under stress. This stress-related measurement may be gained from light induced thermography (LIT) yielding information on diode shunt areas within the solar cell. | 06-28-2012 |

20110100443 | Photovoltaic solar cell device manufacture - A method for manufacturing a photovoltaic solar cell device includes the following. A p-n junction having a first doping density is formed. Formation of the p-n junction is enhanced by introducing a second doping density to form high doped areas for a dual emitter application. The high doped areas are defined by a masking process integrated with the formation of the p-n junction, resulting in a mask pattern of the high doped areas. A metallization of the high doped areas occurs in accordance with the mask pattern of the high doped areas. | 05-05-2011 |
