toxic elements have been predicted. These materials, often made in thin film form and
known to absorb light 10–1000 times more e ciently than crystalline silicon, could lower
module cost and enable broader solar deployment. One such material is zinc tin nitride
(ZnSnN 2), a II-IV-nitride analog of the III-nitride materials, which was identified as a suitable
solar absorber due to its direct bandgap, large absorption coefficient, and disorder-driven …
