Synthesis of Photoactive Ternary Cadmium Sulfoselenide Thin Film via Cost-effective Chemical Technique for Solar Cell Application-Juniper Publishers
JUNIPER PUBLISHERS- ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract We have successfully developed arrested precipitation technique for synthesis of photoactive Cd(S 0.8 Se 0.2 ) thin film. Synthesized thin film were characterized for optical, structural, morphological and compositional analysis using UV–Vis spectrophotometer, Xray Diffraction (XRD), Field-Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive Spectroscopy (EDS) analyzer techniques. Optical study shows linear nature of plot confirms direct allowed transition with optical band gap energy 2.13eV. Pure phase hexagonal nanocrystalline thin film formation confirmed through XRD pattern. FESEM micrographs indicate construction of void free and well-adherent twisted nest-like surface morphology containing tremendous grown flakes over substrate. Presence of Cd2+, S2- and Se2- elements confirmed by EDS spectrum. Finally, synthesized thin film show power conversion efficiency of 0.37 %. Keywords: ...
