Description
Off-stoichiometric kesterite-type Cu2ZnSnSe4 (CZTSe) is doped with Li, Na, K by two different methods. Adding dopants as chlorides directly during the solid-state synthesis from pure elements is compared to a post deposition approach. The samples are analysed by XRD with subsequent Rietveld refinements in combination with EMPA for spatially resolved compositional information and bandgap energy is characterized by DRIFTS.
