Cu-Zn disorder in stoichiometric and non-stoichiometric Cu2ZnSnS4/Cu2ZnSnSe4

Cu-Zn disorder is unavoidable but plays an important role in high-efficiency Cu2ZnSnS4 and Cu2ZnSnSe4 solar cells. Using the cluster expansion method along with Monte Carlo (MC) simulations, we study the Cu-Zn disorder, considering cases both with and without vacancies. We find that the 2a, 2c, and...
