The present invention relates to a method and an apparatus for determining the position of a substrate within a closed chamber, wherein the substrate is moved within the chamber by a transport system comprising at least one rotating shaft. A load-converting element is provided adjacent to at least one of the rotating shafts, wherein the load-converting element detects a load acting on the at least one rotating shaft and converts it into an electrical parameter. While no substrate is present on the at least one rotating shaft, a first output signal corresponding to a first value of the electrical parameter is measured. The output signal is then monitored and a presence of the substrate on the at least one rotating shaft is detected when the output signal differs from the first output signal by at least a predetermined amount.

The present invention proposes a method to form a CdSeTe thin film with a defined amount of selenium and with a high quality. The method comprises the steps of providing a base substrate and of depositing a partial CdSeTe layer on a first portion of the base substrate. The step of depositing a partial CdSeTe layer is performed at least twice, wherein a predetermined time period without deposition of a partial CdSeTe layer on the first portion of the base substrate is provided between two subsequent steps of depositing a partial CdSeTe layer. The temperature of the base substrate and the CdSeTe layer already deposited on the first portion of the base substrate is controlled during the predetermined time period such that re-evaporation of Cd and/or Te from the CdSeTe layer already deposited takes place.
