Abstract
A multi junction photovoltaic cell for converting light into electrical energy, comprising a substrate (3) having a surface (31), wherein a region (4) at the surface (31) of the substrate (3) is doped such that a first p-n junction is formed in the substrate (3). The photovoltaic cell has a nanowire (2) that is arranged on the surface (31) of the substrate (3) at a position where the doped region (4) is located in the substrate (3), such that a second p-n junction is formed at the nanowire (2) and in series connection with the first p-n junction.
