NOVELTY - Producing an article comprising a combination of photovoltaic cell structure and an interconnection structure (22a), comprises: providing photovoltaic cell structure comprising thin film semiconductor material supported on an upwardly facing surface of a first metal based foil; providing the interconnection structure comprising additional non-conductive material and conductive material (23) not present during production of the photovoltaic cells, where the interconnection structure has a substantially planar upper surface; and combining the interconnection structure with the cell structure.    USE - The method is useful for producing an article comprising a combination of photovoltaic cell structure and an interconnection structure.    ADVANTAGE - The method: utilizes the interconnection structure, which promotes facile series electrical and mechanical assembly of multiple photovoltaic cells (claimed) without the requirement to remove material to expose a top surface of the bottom electrode, and allows very high surface conductivity, thus allowing current transport over an expansive surface of a back electrode while accomplishing secure positioning of the cells; provides the article which exhibits improved efficiency, sufficient strength, good electrical and mechanical joining characteristics, and is prevented from environmental and electrical deterioration; provides good ohmic contact between the interconnection structure and photovoltaic structure; minimizes resistive losses involved in current collection; and is cost effective.    DETAILED DESCRIPTION - Producing an article comprising a combination of photovoltaic cell structure and an interconnection structure (22a) (where the interconnection structure is designed to promote facile series electrical and mechanical assembly of multiple photovoltaic cells), comprises: providing the photovoltaic cell structure comprising thin film semiconductor material supported on an upwardly facing surface of a first metal based foil, where the cell structure has a continuous form; providing the interconnection structure comprising additional non-conductive material and conductive material (23) not present during production of the photovoltaic cells, where the interconnection structure has a substantially planar upper surface; and combining the interconnection structure with the cell structure, where (a) the first metal based foil overlays portions of both the additional non-conductive and conductive materials, (b) the portion of non-conductive material is positioned between the first metal based foil and portion of additional conductive material to ensure that the additional conductive material is not in ohmic contact with the first metal based foil, and (c) the cell structure is provided to the combining step in the continuous form.
