Claim Text:
1. A process for producing a photovoltaic module comprising a plurality of solar cells in a thin-film structure, wherein the process comprises: producing successively: a back-face electrode, a photovoltaic layer obtained by annealing a precursor layer, wherein the precursor layer comprises metallic precursors, and a second semiconductor layer in order to create a p-n junction with the photovoltaic layer, characterized in that the precursor layer is deposited on the back-face electrode in a localized manner, so the precursor layer is not deposited on at least one area of the back-face electrode located between two adjacent solar cells of the plurality of solar cells, wherein the annealing of the precursor layer modifies the at least one area, wherein the at least one area has a greater resistivity than the back-face electrode not part of the at least one, so as to ensure electrical isolation between two adjacent solar cells.
