METHOD FOR MANUFACTURING A PHOTOVOLTAIC MODULE WITH TWO ETCHING STEPS P2 AND P3 AND CORRESPONDING PHOTOVOLTAIC MODULE

The invention relates to a method for manufacturing a photovoltaic module comprising a plurality of solar cells in a thin-layer structure, in which the following are consecutively formed: an electrode on the rear surface (41), a photovoltaic layer (46) obtained by depositing a layer (42) of precursors and by annealing such as to convert the precursors into a semiconductor material, and another semiconductor layer (43) in order to create a pn junction with the photovoltaic layer (46); characterised in that the layer (42) is deposited in a localised manner, such as to leave free at least one area (410) of the electrode on the rear surface (41) placed between two adjacent cells, wherein the annealing step modifies said area (410) which has higher resistivity than the rest of the electrode on the rear surface (41), such as to provide electric insulation between two adjacent cells.
