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 (), a photovoltaic layer () 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 () in order to create a pn junction with the photovoltaic layer (); characterized in that the metal precursors form, on the electrode on the rear surface (), 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 () of the layer of metal precursors in the metal state at said break.

Method for manufacturing a photovoltaic module with annealing for forming a photovoltaic layer and electrically conducting region

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 (), a photovoltaic layer () obtained by depositing a layer () of precursors and by annealing such as to convert the precursors into a semiconductor material, and another semiconductor layer () in order to create a pn junction with the photovoltaic layer (); characterized in that the layer () is deposited in a localized manner, such as to leave free at least one area () of the electrode on the rear surface () placed between two adjacent cells, wherein the annealing step modifies said area () which has higher resistivity than the rest of the electrode on the rear surface (), such as to provide electric insulation between two adjacent cells.
