Title: Contrasting the material chemistry of Cu2ZnSnSe4 and Cu2ZnSnS(4-x)Sex

Earth-abundant sustainable inorganic thin-film solar cells, independent of precious elements, pivot on a marginal material phase space targeting specific compounds. Advanced materials characterization efforts are necessary to expose the roles of microstructure, chemistry, and interfaces. Here, the earth-abundant solar cell device, Cu2ZnSnS(4-x)Sex, is reported, which shows a high abundance of secondary phases compared to similarly grown Cu2ZnSnSe4.
