Kinetics of the reactive crystallization of CuInSe2 and CuGaSe2 chalcopyrite films for solar cell applications

Abstract The reaction kinetics of stacked layers of binary In-, Ga- and Cu-selenides is investigated by differential thermal analysis using different constant heating rates. We found that the kinetics of the formation of CuInSe 2 depends on the binary selenides being present. The kinetic parameters of the reactive crystallization of CuInSe 2 and CuGaSe 2 were derived.
