A bifacial solar cell including a semiconductor substrate wafer, a first active area of a first conductivity type provided on at least a part of a first side of the wafer and a second active area of a second conductivity type provided on a second side of the wafter, the edge face of the wafter and the periphery of said first side of the wafter. The first active area and second active area are separated by a distance lambda , the distance lambda allowing a leakage current to flow between the first and second active areas. |
