Recent work has identified a non-zinc-blende-type quaternary semiconductor, Cu2BaSnS4–x Se x (CBTSSe), as a promising candidate for thin-film photovoltaics (PVs). CBTSSe circumvents difficulties of competing PV materials regarding (i) toxicity (e.g., CdTe), (ii) scarcity of constituent elements (e.g...
