A new approach for CuInSe{sub 2} formation by sequential electrodeposition of Cu and In-Se layers and subsequent heat-treatment with elemental selenium in Ar and Ar + H{sub 2} flows is presented. The nature of the precursors and their evolution as a function of the selenization parameters have been studied by X-ray diffraction and X-ray photoelectron spectroscopy analysis. Sample temperature, Se-source temperature, and H{sub 2}/Ar volume ratio in the flow were the subject for optimization. A sample temperature above 400 C is needed to obtain single-phase CuInSe{sub 2} films. An increase in the film crystallinity has been reached by maintaining the Se-source temperature above 400 C. The introduction of H{sub 2} in the selenizing atmosphere has proven to be unsuitable, H{sub 2}Se formation must be avoided because it is more poisonous and less reactive than the elemental selenium vapor.
