Abstract

A method and an arrangement for providing chalcogens as thin layers on substrates, in particular on planar substrates prepared with precursor layers and composed of any desired materials, preferably on substrates composed of float glass, is achieved by forming an inlet- and outlet-side gas curtain for an oxygen-tight closure of a transport channel in a vapour deposition head, introducing an inert gas into the transport channel for displacing atmospheric oxygen, introducing one or more substrates to be coated, the substrates being temperature-regulated to a predetermined temperature, into the transport channel, introducing a chalcogen vapour/carrier gas mixture from a source into the transport channel at the vapour deposition head above the substrates and forming a selenium layer on the substrates by PVD at a predetermined pressure, and removing the substrates after a predetermined process time has elapsed.
