Contrasting the Material Chemistry of Cu2ZnSnSe4and 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. Herein, 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.
