NOVELTY - The device (150a-150d) has electrically conducting elements (152a, 152b) i.e. metal fingers, formed of single piece of material that is capable of electrically connecting first electrical contacts (110, 112) that partially cover doped semiconductor regions of a photovoltaic cell (102a), with second electrical contacts that partially cover doped semiconductor regions of another photovoltaic cell (102b). An electrically insulating portion is arranged on and/or in the electrically conducting element to insulate the electrically conducting elements from the electrical contacts.    USE - Device for electrically interconnecting photovoltaic cells i.e. rear-face contacts type photovoltaic cells, with each other in series in a photovoltaic module (claimed).    ADVANTAGE - The electrically insulating portion is arranged on and/or in the electrically conducting element to insulate the electrically conducting elements from the electrical contacts, so that the electric connection between the electrical contacts can be fulfilled by bus bars and the electric connection between the photovoltaic cells can be fulfilled by a metal ribbon or device, thus facilitating the realization of electrical connections between the photovoltaic cells in an inexpensive manner.    DETAILED DESCRIPTION - The semiconductor doped regions of the photovoltaic cells are formed in form of fingers. INDEPENDENT CLAIMS are also included for the following:    (1) a method for realizing a device for electrically interconnecting photovoltaic cells with each other    (2) a method for interconnecting photovoltaic cells with each other    (3) a method for realizing a photovoltaic module.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a photovoltaic module with three photovoltaic cells electrically interconnected with each other in series by two interconnection devices.
