| 20090255565 | THIN FILM SOLAR CELL STRING - Thin film PV cells and strings of such cells that may be electrically joined with conductive tabs or ribbons. A semi-flexible, electrically conductive adhesive is applied to join the tabs to the front and back of a cell, providing a conductive pathway between the tab and solar cell, with good adhesion to both. The tabs may be constructed of one or more materials having a thermal expansion coefficient that closely matches that of the substrate material of the cells, so that when the string or module is subsequently heated, mechanical stress between the tab and solar cell is minimized. The semi-flexible nature of the ECA also acts to relieve stress between the tab and the solar cell, decreasing the possibility of adhesion failure at critical locations. One or more dielectric materials may be applied to the PV cells and/or the tabs in regions where a tab crosses the edge of a cell, to avoid electrical shorting between the negative and positive electrodes of the cell. | 10-15-2009 |

| 20100147356 | Thin film solar cell string - Thin film photovoltaic cells and strings of cells that may be electrically joined in series by a conductive carrier web that underlies the positive polarity side (bottom side) of the cells. Electrical contact between the positive polarity side of a cell and the carrier web may be made through electrically conductive material such as conductive adhesive disposed between the carrier web and one or more portions of the bottom surface of each cell. Electrical contact between the negative polarity (top side) of a cell and the carrier web may be made through one or more apertures formed in the cell. An electrically conductive material may be disposed in the apertures for this purpose, in conjunction with a dielectric to line the aperture and avoid an electrical short between the opposite polarities of a given cell. | 06-17-2010 |
