Claim 14:
15. A method for manufacturing a photovoltaic cell, the method comprising the steps of:
providing a silicon substrate having two opposite main surfaces;
applying a POx- and Al-comprising-layer directly on a first main surface of the two opposite main surfaces of the silicon substrate; and
applying a capping layer structure on top of the PO, and Al-comprising-layer to cover the POx- and Al-comprising-layer,
wherein POx- and Al-comprising-layer is a mixed AlPxOy-film, and a the ratio between the atomic percentage of phosphorus and phosphorus+aluminum (P/(P+Al)) in the POx- and Al-comprising-layer is from at least 0.6 to less than 1.
