Abstract
Thin film PV cells and strings of such cells that may be electrically joined with electrical conductors or electroconductive patterns are disclosed. The electrical conductors wrap or fold around the PV cells to form an electrical series connection among those cells. The electrical conductors may be formed or deposited on an electrically insulating sheet, which is then wrapped or folded around those cells. By constructing the electrical conductor and positioning the cells appropriately, an electrical connection is formed between one polarity of a given cell and the opposite polarity of the adjacent cell when the sheet is folded over. One or more dielectric materials may be applied or attached to exposed edges of the cells or conductive traces prior to folding the electrical conductors and/or electrically insulating sheet to prevent shorts or failure points.
