Abstract

In the frame of manufacturing a photovoltaic cell a layer (3) of silicon compound is deposited on a structure (1). The yet uncovered surface (3a) is treated in a predetermined oxygen (O2) containing atmosphere which additionally contains a dopant (D). Thereby, the silicon compound layer is oxidized and doped in a thin surface area (5).
