摘要：
The present invention relates to a solar cell (1) comprising
i) 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);
ii) a conductive polymer layer (4) that at least partially covers the back side (2b) of the substrate; and
iii) an electrode (5) that at least partially covers the conductive polymer layer (4) one the side of the conductive polymer layer (4) that is facing away from the substrate (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.
