ABSTRACT:
A contact system for thin film solar cells, which guarantees that charge carrier transport without a barrier layer takes place from the semiconductor layer facing the light source to the front contact in such a manner that, among others, long term negative influences by the front contact on the semiconductor layer will not take place. To this end the front contact is rendered passive against the semiconductor layer by modifying its chemical potential, at least in the actual contact area, to be matched to the chemical potential of the semiconductor layer, or by forming a chemically inert system acting as a reaction barrier between the front contact and the semiconductor layer.
