20130061401 | PROCESS FOR TREATING WOVEN GLASS CLOTH - A solvent wash employing a polar washing solvent is employed to effectively remove the sizing agent on a woven glass cloth, while retaining the tensile strength of the woven glass cloth. Loss of tensile strength of the woven glass cloth due to removal of a sizing agent from the woven glass cloth is compensated by simultaneous or subsequent deposition of a coupling agent on surfaces from which the sizing agent is removed. The concurrent removal of the sizing agent and deposition of the coupling agent provides an effective removal of the sizing agent while maintaining sufficient tensile strength to structurally support the woven glass cloth. Further, integration of the removal of the sizing agent and the simultaneous deposition of the coupling agent in the washing solvent in a same processing step can provide a cost-effective manufacturing method for forming a finished woven glass cloth. | 03-14-2013 |

20150020863 | SEGMENTED THIN FILM SOLAR CELLS - Use of chemical mechanical polishing (CMP) and/or pure mechanical polishing to separate sub-cells in a thin film solar cell. In one embodiment the CMP is only used to separate the active, thin film layer into sub-cells, with scribing still being used to achieve sub-cell separation in conductive layers above and below the active, thin film layer. Also, the active layer may be placed over a series of protrusions so that the CMP removes the active layer that is over the protrusion, while leaving intact the flat, planar portions of the active layer. In this way, the removed active layer, from over the protrusions then becomes the division between sub-cells in the active layer. | 01-22-2015 |
