20140150850 | SOLAR CELL COATING - Embodiments of the present invention help prevent Potential-Induced Degradation (PID) in solar cell modules. A solar cell module according to one embodiment of the present invention comprises a glass sheet, a frame covering at least a portion of the glass sheet, a plurality of solar cells at least partially covered by the glass sheet, and a hydrophobic coating covering at least a portion of the frame and at least a portion of the glass sheet. | 06-05-2014 |
20140057388 | Systems and Methods for Depositing and Charging Solar Cell Layers - Systems and methods of the present invention may be used to charge a layer (such as a passivation layer and/or antireflective layer) of a solar cell (e.g., wafer) with a positive or negative charge. The layer may retain the charge to improve operation of the solar cell. The charged layer may include any suitable dielectric material capable of retaining either a negative or a positive charge. Systems and methods of the present invention permit in-situ charging of a layer. Charging of a layer may be accomplished during or after deposition of the layer including after completing the whole solar cell process, in other words, on a finished cell. | 02-27-2014 |
20140057387 | Systems and Methods for Depositing and Charging Solar Cell Layers - Systems and methods of the present invention may be used to charge a layer (such as a passivation layer and/or antireflective layer) of a solar cell (e.g., wafer) with a positive or negative charge. The layer may retain the charge to improve operation of the solar cell. The charged layer may include any suitable dielectric material capable of retaining either a negative or a positive charge. Systems and methods of the present invention permit in-situ charging of a layer. Charging of a layer may be accomplished during or after deposition of the layer including after completing the whole solar cell process, in other words, on a finished cell. | 02-27-2014 |

20130133578 | SYSTEMS FOR CHARGING SOLAR CELL LAYERS - Systems and methods of the present invention can be used to charge a charge-holding layer (such as a passivation layer and/or antireflective layer) of a solar cell with a positive or negative charge as desired. The charge-holding layer(s) of such a cell can include any suitable dielectric material capable of holding either a negative or a positive charge, and can be charged at any suitable point during manufacture of the cell, including during or after deposition of the passivation layer(s). | 05-30-2013 |
20130089944 | SOLAR CELL SILICON WAFER PROCESS - In the production of silicon solar cells wherein the process includes a dopant diffusion to form a pn junction, a back surface field layer, or a front surface field layer, resulting in the formation of a doped glass surface, a HF vapor etch is utilized to remove the doped glass layer and expose the wafer surface. The exposed surface is subjected to an oxygen treatment for predetermined times and temperatures to alter the surface state. The HF vapor etch followed by the oxygen treatment, or chemical oxidation, results in significant improvement in solar cell electrical properties. | 04-11-2013 |
