Abstract

A solar cell has electrical conductors applied on a pattern of electric contacts on a front surface and extending transversely relative thereto with a portion projecting beyond the edge of the solar cell. The formation of the electrical pattern includes at least two elongated portions interconnected by a return portion which extends beyond the one edge. This return portion provides a stiffening suitable for reliable interconnection to an additional solar cell to achieve a connection of two conductors in the projecting region.
