EFFECT OF THE SELENIUM CONTENT IN THE OPTICAL PROPERTIES OF THE KESTERITE Cu2ZnSnS4-xSe x PHASES

EFFECT OF THE SELENIUM CONTENT IN THE OPTICAL PROPERTIES OF THE KESTERITE Cu2ZnSnS4-xSe x PHASES

Polycrystalline Cu2ZnSnS4-xSe x (X=1, 2, 3) compounds were synthesized by conventional solid-state reactions. The samples were characterized by powder X-ray diffraction (XRD), energy-dispersive X-ray analysis (SEM-EDS), Raman spectroscopy, diffuse reflectance UV-vis and Photoluminescence. All ofphas...
