Abstract

In different exemplary embodiments, a solar cell is provided, including: a substrate with a first region and a second region, wherein the first region includes at least a first electrical conductivity and the second region includes at least a second electrical conductivity which is greater than the first electrical conductivity; and a passivation on the surface of the substrate; and a contact-structure on the surface of the substrate, wherein the contact-structure includes a plurality of contacts; wherein two contacts of the plurality of contacts are disposed at a first distance with respect to each other in the first region; wherein two further contacts of the plurality of contacts are disposed at a second distance with respect to each other in the second region; and wherein the second distance is greater than the first distance.
