NOVELTY - The photovoltaic module comprises a sintered silicon support comprising integrated photovoltaic cells (20), which are connected in series and isolated from each other by oxidized parts (14) of sintered silicon support, and vias (24) for connecting cells. The oxidized parts extend from one face to another of the support. Each cell has a first area heavily doped by a first type in and/or on the support and a second area laid partly on the first area. The doping of the second area is less than the doping of the first area, which defines a first terminal of the photovoltaic cell.    USE - Used as a photovoltaic module such as solar cell.    ADVANTAGE - The photovoltaic module can be economically and easily manufactured with excellent efficiency, high performance and improved life-time.    DETAILED DESCRIPTION - The photovoltaic module comprises a sintered silicon support comprising integrated photovoltaic cells (20), which are connected in series and isolated from each other by oxidized parts (14) of sintered silicon support, and vias (24) for connecting cells. The oxidized parts extend from one face to another of the support. Each cell has a first area heavily doped by a first type in and/or on the support and a second area laid partly on the first area. The doping of the second area is less than the doping of the first area, which defines a first terminal of the photovoltaic cell. Each of photovoltaic cells further comprises a third area doped by a second type material different from the first type material and arranged on the second area, and a fourth area strongly doped with a second type material different from the first type material and laid under the second area. The third area defines a second terminal of the cell, and the fourth area defines a second terminal of the cell. The cells have the form of strips extending from one edge to another of the module. An INDEPENDENT CLAIM is included for a process for manufacturing a photovoltaic module.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a photovoltaic module.
