A tandem photovoltaic structure including, from the rear face to the front face: a first solar cell—with a silicon heterojunction: a first layer of a first conductivity type made of amorphous silicon and a substrate of doped crystalline silicon disposed between two layers of intrinsic amorphous silicon, a recombination zone comprising a layer of nanocrystalline or monocrystalline silicon of the second conductivity type, a second solar cell comprising an active layer made of a perovskite material and a second layer of a second conductivity type. The recombination zone further includes a layer of the first conductivity type in contact with the active layer of the second cell or a layer of nanocrystalline or monocrystalline silicon of the first conductivity type in contact with the active layer of the second solar cell.
