Abstract

The invention relates to a solar cell comprising front contacts on a front side, for collecting electrons, and a connection device for connecting to the front contacts. The front contacts are in the form of thin contact fingers, different lengths of connection wires leading from the contact fingers to the connection device. Different lengths of the connection wires extend from the connection device to at least one contact finger. Almost all of the longer connection wires are electrically connected several times, along the course or the length thereof, to different contact fingers.
