Claim Text:
1. A method for manufacturing a photovoltaic module comprising at least two series-connected adjacent photovoltaic cells, said method comprising: forming an insulating substrate; forming a stack comprising: forming at least one connection area dividing the stack into a first and a second electrically-adjacent photovoltaic cells only connected by an electric path between a portion of the first conductive layer of the first cell and a portion of the second conductive layer of the second cell, wherein the forming of said electric path comprises: forming a first trench in the stack from the second conductive layer to the substrate; forming a second trench separate from the first trench, from the second conductive layer to the first conductive layer; and depositing a conductive solution on an area of the second semiconductor layer comprising the first trench and at least a portion of the second trench located on a side of the first trench, the geometry of the trenches, the thickness of the second conductive layer, and the quantity and the properties of the conductive solution on deposition thereof being selected so that the conductive solution does not penetrate into the first trench all the way to the first conductive layer and penetrates into the second trench all the way to the first conductive layer.
