20140273331 | METHODS FOR WET CHEMISTRY POLISHING FOR IMPROVED LOW VISCOSITY PRINTING IN SOLAR CELL FABRICATION - A method of fabricating a solar cell is disclosed. The method includes forming a polished surface on a silicon substrate and forming a first flowable matrix in an interdigitated pattern on the polished surface, where the polished surface allows the first flowable matrix to form an interdigitated pattern comprising features of uniform thickness and width. In an embodiment, the method includes forming the silicon substrate using a method such as, but not limited to, of diamond wire or slurry wafering processes. In another embodiment, the method includes forming the polished surface on the silicon substrate using a chemical etchant such as, but not limited to, sulfuric acid (H | 09-18-2014 |
20150263200 | METHOD OF FABRICATING A SOLAR CELL WITH A TUNNEL DIELECTRIC LAYER - Methods of fabricating solar cells with tunnel dielectric layers are described. Solar cells with tunnel dielectric layers are also described. | 09-17-2015 |
20150280029 | METALLIZATION OF SOLAR CELLS - Approaches for the metallization of solar cells and the resulting solar cells are described. In an example, a method of fabricating a solar cell involves forming a plurality of alternating N-type and P-type regions in or above a substrate. The method also involves forming a metal seed layer on the plurality of alternating N-type and P-type regions. The method also involves patterning at least a portion of the metal seed layer at regions in alignment with locations between the alternating N-type and P-type regions. The method also involves, subsequent to the patterning, etching to form trenches at the locations between the alternating N-type and P-type regions, isolating the alternating N-type and P-type regions from one another. | 10-01-2015 |
