Method for manufacturing a photovoltaic module and photovoltaic module thus obtained

A method for manufacturing a photovoltaic module, comprising at least two electrically connected photovoltaic cells, the method comprising the following steps:

• a) providing an electrically insulating substrate covered with a layer of a first electrically conducting material;
• b) forming, on said layer, at least one furrow defining first and second lower electrodes, electrically isolated from one another by said furrow;
• c) forming, on each of said lower electrodes, a stack comprising at least:
• an upper electrode formed by a layer of a second electrically conducting material, and a layer of a photo-active material positioned between the lower and upper electrodes, wherein each of the first and second lower electrodes respectively forming a first and second photovoltaic cell with the corresponding stack;
• and
• d) forming an electrical connection between the upper electrode of the first photovoltaic cell and the second lower electrode;
• the method being characterized in that it comprises the following steps, between steps b) and c):
• e) forming a first electrically insulating strip in the furrow and above said furrow, said strip forming a relief relative to the first and second lower electrodes;
• and
• f) forming a second electrically insulating strip on the second lower electrode, said first and second electrically insulating strips being substantially parallel and delimiting an inactive area on said second lower electrode;
• in that the stack formed in step c) on the second photovoltaic cell is positioned outside the inactive area.
