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 |
