摘要

The module has back side-contacted solar cells, and connecting units for mechanical and/or electrical connection of the adjacent solar cells, where the connecting units comprise ends (20, 30) with contacting units. The contacting units comprise a contacting zone with two soldering surfaces (1) and a strain-and/or pressure relief unit (2) arranged between opposite soldering surfaces. The strain-and/or pressure relief unit is partly arranged circularly or ellipsoidally. Another strain-and/or pressure relief unit (5) is partly fixed with a circular or ellipsoidal recess.
