CuInSe2, Cu(In,Ga)Se-2 and CuIn(Se,S)(2) films were grown on glass and on SnO2 thin films by using a close-spaced vapor transport in closed tube with iodine. The SnO2 thin films were grown from a pyrosol method. The samples were studied by X-ray and scanning electron microscope analysis. We show that the CuLnSe(2) films grown on SnO2 thin films can have a very strong (100) (or (001)) preferred orientation, probably induced by the substrate, and not by the experimental conditions.
