Photovoltaic cell and a method for manufacturing the same

A photovoltaic cell is disclosed comprising a silicon substrate having two opposite main surfaces, wherein a first main surface of the two main surfaces is covered with a passivation layer stack, comprising a POx-and Al -comprising-layer covering the first main surface, and a capping layer with covers the POx-and Al-comprising-layer. Also disclosed is a method for manufacturing a photovoltaic cel
