Abstract
In an apparatus for producing thin layers on substrates for solar cell production, wherein the thin layers are applied by an APCVD process at temperatures of more than 250° C., the substrates are conveyed on a horizontal conveyor path and coated by means of an APCVD coating in continuous operation. The conveyor path has conveyor rollers, which consist of a temperature-resistant, non-metallic material, preferably of ceramic. A heating device and/or a purge gas feeding device is/are arranged on that side of the conveyor path which is remote from the coating apparatus.
