Influence of a thermal annealing procedure on kesterites
Kesterite is a mineral with a formular Cu2ZnSn(S,Se)4. It is a very promising material for future photovoltaics (PV), since the composition is non-toxic and the source materials are very cheap in relevance to other PV-materials.
The main goal of the project is to observe a change in the structure or the composition of the material after a thermal annealing procedure. In a thermal annealing the material is heated up to a few degrees under the melting point to alter the chemical and/or physical properties.
The material is characterized by X-ray pulver diffractometrie (XRD) and wavelength dispersive x-ray spectroscopy (WDX) before and after the annealing. A diversity in the samples can be observed.
Wonderful picture, good and telling headline and a very clear text! Well done.
Hi Daniel, thanks for this very short introduction and the lovely photo of the kesterite pulver. I really like it!
