This research examines the effects of Coomassie Brilliant Blue (CBB) incorporation on Cu-Sb-S nanocomposite thin films synthesized through hydrothermal methods. Samples were prepared with varying CBB concentrations (0, 0.01, 0.03, and 0.05 gm) comprehensively known to have structural, morphological, optical, electronic characteristics. XRD analysis successfully verified forming crystalline phases, patterns showing characteristic peaks that evolved increasing content. Based X-ray diffraction results. The crystal formations products, Cu3SbS3, Cu3SbS4, Na2C2O4, are cubic, Tetragonal, Monoclinic symmetry respectively. FE-SEM imaging revealed a uniform nanostructure distribution controlled morphology across all compositions, confirming successful integration into host matrix. Optical characterization demonstrated systematic modifications in transmission absorption properties an concentration, indicating effective band structure modification. optical direct gab values proved UV-visible be 1.4,1.5,1.6 1.7 eV estimated by Tauc plots for ratio (X= 0,0.01,0.03,0.05 Hall effect measurements p-type semiconductor behavior throughout composition range, notable trend decreasing carrier concentration from 9.53×10¹⁴ 3.21×10¹⁴ cm⁻³ accompanied significant enhancement mobility 4.231 27.654 cm²/V·s as content increased. These findings demonstrate modification system's optoelectronic incorporation, suggesting potential applications photovoltaic devices systems requiring high mobility. It can also used good absorbent layer solar cells.
