Abstract
A solar cell segment includes a substrate defining a rear side including a number of base doped regions and emitter doped regions. A dielectric layer and at least one metallizing layer are disposed on the rear side of the substrate. The at least one metallizing layer is structured in an interdigital comb-shaped contact deck arrangement and defines base contact decks for a number of base doped regions and emitter contact decks for a number of base doped regions. The at least one metallization layer is disposed between the rear side of the substrate and the dielectric layer. At least one first row of first contact openings is formed in the dielectric layer lying in a region of the base contact decks and at least one second row of second contact openings is formed in the dielectric layer lying in a region of the emitter contact decks.
