A solar cell includes a semiconductor layer, a collecting layer for collecting free charge carriers from the semiconductor layer and a buffer layer which is arranged between the semiconductor layer and the collecting layer. The buffer layer is designed as a tunnel contact between the semiconductor layer and the collecting layer. The buffer layer essentially includes a material with a surface charge density of at least 10cm, preferably of at least 5&#xd7;10cm, and more preferably of at least 10cm.

Solar cell

A semiconductor device, in particular a solar cell, comprises a semiconductor substrate having a semiconductor substrate surface and a passivation composed of at least one passivation layer which surface-passivates the semiconductor substrate surface, wherein the passivation layer comprises a compound composed of aluminum oxide, aluminum nitride or aluminum oxynitride and at least one further element.

Semiconductor device, in particular solar cell

The invention relates to a semiconductor apparatus and a method of fabrication for a semiconductor apparatus, whereby the semiconductor apparatus includes a semiconductor layer and a passivation layer arranged on a surface of the semiconductor layer and serving for passivating the semiconductor layer surface, whereby the passivation layer comprises a chemically passivating passivation sublayer and a field-effect-passivating passivation sublayer, which are arranged one above the other on the semiconductor layer surface.
