NOVELTY - A photovoltaic device comprises first and second cells (62a, 62b) having photovoltaic coating on flexible, conductive sheet creating positive and negative sides, where negative side of each cell has conductive grid with at least one hole, each hole having walls covered by dielectric material (86); and a carrier having mounting surface for electrically connecting cells in series via conductive material (82) which is electrically conductive adhesive (90), and is configured to electrically connect grid of first cell to positive side of second cell via hole in first cell.    USE - In thin-film solar cells.    ADVANTAGE - The photovoltaic cells are interconnected into strings with reduced costs, while maintaining and improving the ability of the cell to withstand stress, thus providing improved strings which can be processed into discrete solar cells. The electrically conductive adhesive can be curable at less than 225 degrees C to avoid possible heat damage to other components of the cell.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) string of thin film photovoltaic cells comprising thin-film photovoltaic cells having top and bottom surface; at least one aperture extending from top to bottom surface; electrically conductive carrier web (W1) underlying bottom surface of cells, where top surface of each cell is electrically connected to carrier web through first portion of electrically conductive adhesive disposed in aperture, and bottom surface of each cell is electrically connected to carrier web through a second portion, and electrically conductive adhesive is disposed between carrier web and bottom surface of each cell; and    (2) solar cell array comprising first and second thin film photovoltaic cells, electrically conductive material disposed with aperture of each cell and configured to transfer electric current from top surface of each cell towards bottom surface; and electrically conductive carrier web (W1).
