Solar-cell

A solar cell comprising a wafer-shaped semiconductor member of first conductivity type, said semiconductor member having a rear side with a rear side contact affixed thereto and having a front side with a conduction path system affixed thereto as a front side contact, wherein a region (2) of second conductivity type is disposed on all sides of the semiconductor member (1) of first conductivity type to form a pn-junction, wherein the rear side contact (4, 5, 6) ohmically contacts the semiconductor member (1) of first conductivity type by penetrating the region (2) of the second conductivity type and consists, starting from the semiconductor member, of the layer sequence titanium-palladium-silver, and wherein the pn-junction is severed on said rear side of said semiconductor member along a path that surrounds said rear side contact.
