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, said module comprising an insulating substrate covered with a layer of a first conductive material;

• the method comprising the following steps:
• a) forming, on the layer of first material, a groove defining a first and a second lower electrodes, electrically isolated from one another;
• and
• b) forming, on each of said lower electrodes, a stack comprising at least:
• an upper electrode formed by a layer of a second electrically conductive material;
• and a photo-active layer positioned between the lower and upper electrodes;
• each of the first and second lower electrodes respectively forming a first and a second photovoltaic cell with the corresponding stack;
• wherein step b) is carried out after step a);
• the method further comprises the following steps:
• c) formation of a first insulating strip on the layer of first material, so as to cover a location of the groove;
• said first strip comprising a first and second adjacent portion, respectively oriented toward the first and toward the second lower electrodes;
• then
• d) formation of a conductive strip on the layer of first material, said conductive strip covering the second portion and leaving the first portion of the first insulating strip free;
• said conductive strip comprising a first and second adjacent portion, respectively oriented toward the first and toward the second lower electrode, said first portion forming a relief relative to the first insulating strip;
• then
• e) forming a second insulating strip on the layer of first material, said second strip covering the second portion and leaving the first portion of the conductive strip free;
• wherein at least steps d) and e) being carried out between steps a) and b);
• and
• wherein in step b), the upper electrodes of the first and second photovoltaic cells are respectively formed in contact with, and away from, the first portion of the electrically conductive strip.
