The invention relates to a solar cell which consists of a doped semiconductor base body and metallic connection contacts on the front and rear sides. For interconnection with further solar cells to form solar modules in series or parallel connection, at least one of the connection contacts comprises a connector contact which is homogeneously integrated with it, protrudes from the semiconductor base body and is deformable.

Method of manufacturing a solar cell

The invention relates to a solar cell for exposure to light rays on both sides. The solar cell contains only one pn junction on one surface side of the semiconductor body. The base of the solar cell is uniformly and less strongly doped than the thin surface zone of the conduction type opposite to that of the semiconductor base. Both zones of the solar cell are in contact with a structured conduction path system on opposite surface sides.
