Quantitative Analysis Using X-ray Diffraction. Jeremy R. Gersztyn. Oregon State University, Department of Chemistry. December 5, 2005

Abstract:

Powder x-ray diffraction was used to construct calibration curves of peak area versus for known amounts of impurities added to a possible solar cell material, Cu₂ZnSnSe₄, and from this a detection limit of each impurity was determined. The compounds which detection limits were determined are Cu₂Se and SnSe and there detection limits were determined to be 19.2 mol% and 1.38 mol% ± 0.10 mol% respectively. The detection limit for Cu₂Se may not be accurate due to the observed non-linearity.
