In the context of my master's thesis I am assigned with the construction and characterization of an In-Situ X-Ray Fluorescence Probational Chamber. The source used for the fluorescence excitation is a copper rotating anode with a "white" X-ray spectrum (up to 44 keV). The detection is performed by a Si detector from AmpTek. The "Domed Hot Stage" from Anton Paar serves as a probational chamber, which enables temperatures up to 1100 °C. It is possible to operate with different temperature sequences in vacuum or various process gas atmospheres while performing in-situ X-ray flourescence measurements. The whole process control has been realized with LabView.
New insight in the creation process of precursor metal layer systems of CuZnSnSe thin layer solar cells with a Mo back electrode shall be gained by this In-Situ X-Ray Fluorescence Probational Chamber.
