20130213469 | HIGH EFFICIENCY SOLAR CELL STRUCTURES AND MANUFACTURING METHODS - Fabrication methods and structures relating to multi-level metallization for solar cells as well as fabrication methods and structures for forming back contact solar cells are provided. | 08-22-2013 |
20130217172 | LASER PROCESSING FOR HIGH-EFFICIENCY THIN CRYSTALLINE SILICON SOLAR CELL FABRICATION - Laser processing schemes are disclosed for producing various types of hetero-junction and homo-junction solar cells. The methods include base and emitter contact opening, selective doping, and metal ablation. Also, laser processing schemes are disclosed that are suitable for selective amorphous silicon ablation and selective doping for hetero-junction solar cells. These laser processing techniques may be applied to semiconductor substrates, including crystalline silicon substrates, and further including crystalline silicon substrates which are manufactured either through wire saw wafering methods or via epitaxial deposition processes, that are either planar or textured/three-dimensional. These techniques are highly suited to thin crystalline semiconductor, including thin crystalline silicon films. | 08-22-2013 |
