NOVELTY - Busbar tape comprises a conductive metal foil; and a nonconductive thermoset adhesive, where the tape is solderable, and the tape is capable of adhering to crystal-silicon photovoltaic material.    USE - The busbar tape is useful for providing solderable surface on photovoltaic solar cell or photovoltaic solar module (claimed).    ADVANTAGE - The silver busbars (or silver paste) on the front and rear surface of solar cells or solar modules can be eliminated or reduced by replacing the silver busbars on the front and rear surface with a solderable tape including a conductive metal foil and a nonconductive adhesive. Busbar tape including a conductive metal foil and a nonconductive adhesive can be applied to the front and rear surface of a solar cell or solar module to provide an electrically conductive surface to which a stringing ribbon can be soldered.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a photovoltaic solar cell comprising a silicon wafer comprising a front surface and a back surface, a busbar tape, where the silicon wafer comprises one or more of silver gridlines on the front surface, where the busbar tape comprises a conductive metal foil; and a nonconductive thermoset adhesive; where the busbar tape is solderable and where the busbar tape is bonded to the front surface of the silicon wafer via the nonconductive thermoset adhesive;    (2) a photovoltaic solar module comprising two or more photovoltaic solar cells, where at least some of the photovoltaic solar cells comprise a silicon wafer comprising a front surface and a back surface, at least one front-side busbar and at least one back-side busbar tape, where the silicon wafer comprises one or more of silver gridlines on the front surface, where the front-side busbar tape comprises: a conductive metal foil; and a nonconductive thermoset adhesive; where the front-side busbar tape is bonded to the front surface of the silicon wafer via the nonconductive thermoset adhesive, and where at least a first photovoltaic solar cell is electrically connected in series to a second photovoltaic solar cell via at least one tabbing ribbon, where one end of at least one tabbing ribbon has been soldered to at least one front-side busbar of the first photovoltaic solar cell and the other end of the tabbing ribbon has been soldered to at least one back-side busbar tape of the second photovoltaic solar cell; and    (3) a method of providing a solderable surface on a photovoltaic solar cell, where the photovoltaic solar cell comprises: a silicon wafer comprising a front surface and a back surface, and a busbar tape, where the silicon wafer comprises one or more of silver gridlines on the front surface where the busbar tape comprises a conductive metal foil; and a nonconductive thermoset adhesive; where the busbar tape is solderable, and the method involves applying the busbar tape to the front surface of the silicon wafer of photovoltaic solar cell, and hot pressing the busbar tape and the photovoltaic solar cell.
