Abstract or Summary
  • Copper antimony sulfide (CAS) is a ternary material that is of research interest for thin film photovoltaic applications due to its high absorption coefficient and tunable bandgap. The material is also ideal for sustainable manufacturing due the constituent elements being earth-abundant and less toxic than solar cell absorbers like gallium arsenide or copper indium gallium selenide. The chalcostibite and famatinite crystal phases of CAS can be feasibly utilized for solar cells. The chalcostibite (CuSbS2) phase was studied in this work using X-ray diffraction, Raman spectroscopy, Secondary Electron Microscopy/Energy Dispersive X-ray Spectroscopy, and X-ray Absorption Near Edge Structure. It was found that depositing a precursor solution and annealing the resulting film in air could synthesize CuSbS2. Subsequently, the crystallinity and the grain size of the synthesized material were increase while maintaining the desired crystal phase using a high temperature sulfur anneal. However, small amounts of impurities were formed during the processing making the method presented not ideal for solar cell applications.
