• A simple and useful thermodynamic approach to the prediction of reactions taking place during thermal treatment of layers of multinary semiconductor compounds on different substrates has been developed. The method, which uses the extensive information for the possible binary compounds to assess the stability of multinary phases, is illustrated with the examples of Cu(In,Ga)Se2 and Cu2ZnSnSe4 as well as other less‐studied ternary and quaternary semiconductors that have the potential for use as absorbers in photovoltaic devices. The solar‐cell materials Cu2ZnSnSe4 and Cu(In,Ga)Se2 (CZTS and CIGS) are taken as a case study to show how thermal stability at surfaces and interfaces can be predicted and rationalized. The authors describe how the annealing conditions can be controlled to maximize the stability—and therefore the quality—of the material.
