The present invention relates to a method for manufacturing a photovoltaic module (10), comprising the following steps: forming, on an electrically conducting material, a furrow (20A) defining a first (18A) and second (18B) lower electrode; then forming, on each lower electrode, a stack (34) comprising at least one upper electrode (36) and an intermediate photo-active layer (38), to form a first (16A) and second (16B) photovoltaic cell, respectively; then forming an electrical connection (17A) between said cells (16A, 16B).Before the stacks, the following are formed: a first insulating strip (22A) in the furrow (20A); and a second electrically insulating strip (24B) on the second lower electrode, delimiting an inactive area (28B) on said second electrode. The stack (34) next formed on the second cell is positioned outside the inactive area.
