An interconnected arrangement of photovoltaic cells is achieved using laminating current collector electrodes. The electrodes comprise a pattern of conductive material extending over a first surface of sheetlike substrate material. The first surface comprises material having adhesive affinity for a selected conductive surface. Application of the electrode to the selected conductive surface brings the first surface of the sheetlike substrate into adhesive contact with the conductive surface and simultaneously brings the conductive surface into firm contact with the conductive material extending over first surface of the sheetlike substrate. Use of the laminating current collector electrodes allows facile and continuous production of expansive area interconnected photovoltaic arrays.
