20110272008 | OXIDE NITRIDE STACK FOR BACKSIDE REFLECTOR OF SOLAR CELL - Embodiments of the invention generally provide methods for forming a multilayer rear surface passivation layer on a solar cell substrate. The method includes forming a silicon oxide sub-layer having a net charge density of less than or equal to 2.1×10 | 11-10-2011 |
20110272024 | MULTI-LAYER SiN FOR FUNCTIONAL AND OPTICAL GRADED ARC LAYERS ON CRYSTALLINE SOLAR CELLS - Embodiments of the invention include a solar cell and methods of forming a solar cell. Specifically, the methods may be used to form a passivation/anti-reflection layer having combined functional and optical gradient properties on a solar cell substrate. The methods may include flowing a first process gas mixture into a process volume within a processing chamber generating plasma in the processing chamber at a power density of greater than 0.65 W/cm | 11-10-2011 |
20120100666 | PHOTOLUMINESCENCE IMAGE FOR ALIGNMENT OF SELECTIVE-EMITTER DIFFUSIONS - Embodiments of the invention generally provide a solar cell formation process that includes the formation of metal contacts over heavily doped regions that are formed in a desired pattern on a surface of a substrate. Embodiments of the invention also provide an inspection system and supporting hardware that is used to reliably position a similarly shaped, or patterned, metal contact structure on the patterned heavily doped regions to allow an Ohmic contact to be made. The metal contact structure, such as fingers and busbars, are formed on the heavily doped regions so that a high quality electrical connection can be formed between these two regions. | 04-26-2012 |
20140060609 | MONOLITHIC MODULE ASSEMBLY FOR STANDARD CRYSTALLINE SILICON SOLAR CELLS - Apparatuses and assembly methods are provided for a monolithic solar cell panel assembly. The assembly comprises an array of solar cells having front electrical contacts and back electrical contacts, wherein a first set of the solar cells in the array are aligned to be electrically connected in series through a back circuit sheet having an array of back metal contacts connected to corresponding back electrical contacts on the first set of solar cells, and through a front circuit sheet having an array of front metal contacts connected to corresponding front electrical contacts on the first set of solar cells. Electrical connections may be made in a lamination step, in which an encapsulant polymer flows into gaps and an interconnect material connects the circuits to form the monolithic solar cell panel assembly. | 03-06-2014 |

20100304527 | METHODS OF THERMAL PROCESSING A SOLAR CELL - Embodiments of the invention contemplate the formation of high efficiency solar cells and novel methods for forming the same. Embodiment of the invention can be used to form a solar cell that has doped regions that act as a back surface field. The methods and apparatus disclosed herein may include the use of a doping source, a rapid annealer and a slow annealer. One embodiment of the methods used to form an improved emitter structure include disposing an amount of a dopant atom in a substrate and performing two or more thermal processing steps to cause the dopant to diffuse deeper into the substrate to achieve a desirable multi-facet doping profile. | 12-02-2010 |
20120040490 | ENHANCED VISION SYSTEM FOR SCREEN PRINTING PATTERN ALIGNMENT - Embodiments of the invention also generally provide a solar cell formation process that includes the formation of metal contacts over heavly doped regions that are formed in a desired pattern on a surface of a substrate. Embodiments of the invention also provide an inspection system and supporting hardware that is used to reliably position a similarly shaped, or patterned, metal contact structure on the patterned heavily doped regions to allow an Ohmic contact to be made. The metal contact structure, such as fingers and busbars, are formed on the heavily doped regions so that a high quality electrical connection can be formed between these two regions. | 02-16-2012 |
