Fermi-Level Engineering on Transition Metal Chalcogenides

Synthesis and analysis of Sb₂S₃ as a thin film photo absorber in tandem solar cells. Furthermore, synthesis and analysis of perovskite chalcogenides thin films. (i.e. BaZrS₃, BaTiS₃, SrZrS₃ and SrZrS₃)

Investigating the possibility of Fermi-level engineering on these perovskites in comparison to their oxide partners in SFB FLAIR, project B07:
