| Summary: | Compounds such as Cu2ZnSnS4 (CZTS) have attracted the concern of investigators of photovoltaic applications due to their abundance of elements and their nontoxic and promising optical characteristics. The impact of the radiofrequency (RF) power on the stoichiometry, structure and optical properties of Cu2ZnSnS4 layers, which were fabricated by the magnetron RF sputtering of a single quaternary target, are examined using different techniques, such as energy dispersive X-ray spectroscopy, X-ray diffraction, field emission scanning electron microscopy, Raman spectroscopy and spectrophotometry. The results indicate that RF power plays a critical role in the stoichiometry of the prepared layers, which in turn changes the crystallinity structure, the thickness of the films, the surface morphology and the variation in the absorption coefficient. The effect of annealing at 450°C in ambient nitrogen on the properties of the prepared film was also investigated. |
