Abstract
The present invention relates to a solar cell (1) comprising a substrate (2) of p-type silicon or n-type silicon, wherein the substrate (2) comprises—a front side (2a) the surface of which is at least partially covered with at least one passivation layer (3) and—a back side (2b), wherein—the back side (2b) of the substrate (2) is at least partially covered with a passivation layer (4) having a thickness sufficient to allow a transport of holes through it, and—the passivation layer (4) on the backside 2b) of the substrate (2) is at least partially cov-ered with a conductive polymer layer (5). The present invention also relates to a process for the preparation of a solar cell, to a solar cell obtainable by this process and to a solar module.
