Abstract: The invention relates to a method for manufacturing a photovoltaic module comprising plurality of solar cells in a thin-layer structure, in which the following are formed consecutively in the structure: an electrode on the rear surface (41), a photovoltaic layer (43) obtained by depositing components including metal precursors and at least one element taken from Se and S and by annealing such as to convert said components into a semiconductor material, and another semiconductor layer (44) in order to create a pn junction with the photovoltaic layer (43); characterized in that the metal precursors form, on the electrode on the rear surface (41), a continuous layer, while said at least one element forms a layer having at least one break making it possible, at the end of the annealing step, to leave an area (430) of the layer of metal precursors in the metal state at said break.
