CONDUCTIVE POLYMER/SI INTERFACES AT THE BACKSIDE OF SOLAR CELLS

摘要

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 passivationlayer (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.
