摘要：
A method for producing a photovoltaic solar cell, including the method steps: A. providing at least one solar cell precursor having at least one base and at least one emitter; B. providing a metal film on a back side of the solar cell precursor, so that the metal film is electrically conductively connected to the base or the emitter, the metal film being formed as an integral component of the back side contact and the solar cell being terminated on the back side. The at least one cell connection region on at least one side of the metal film overhangs the edge of the solar cell precursor by at least 1 mm, preferably by at least 3 mm.
