Patent Number: 6,515,218

Title: Photovoltaic element, process for the production thereof, method forremoving a cover portion of a covered wire, and method for joining acovered wire and a conductor

Abstract: A photovoltaic element having a wire disposed on a surface of thephotovoltaic element for outputting a power generated by the photovoltaicelement, and an electrode electrically joined with the wire while forminga joining portion, wherein the joining portion of the wire and theelectrode has at least a first joining portion and a second joiningportion which is adjacent to the first joining portion, and the secondjoining portion has an elasticity which is greater than that of the firstjoining portion. A process for the production of the photovoltaic element.A method for forming an electrical continuity between a covered wire and aconductor, including a method of removing a cover portion of the coveredwire and a method of joining the covered wire with the conductor.
