Claim 14:
15. A method of manufacturing a solar cell comprising a layer stack comprising at least the following features:
a substrate;
at least one doped region comprising an emitter layer within the substrate;
at least one metallization structure;
a sensor in the form of a strain gauge sensor;
the sensor being integrated in the emitter layer in the layer stack, said method comprising:
providing the substrate;
forming the at least one doped region in or on the substrate comprising forming an emitter layer in the substrate; and
forming the at least one metallization structure on the at least one doped region;
wherein a sensor is integrated into the emitter layer of the layer stack during the forming of the at least one doped region.
