A new sonochemical method for preparation of different morphologies of CuInS۲ nanostructures

چکیده مقاله

CuInS2 nanostructures were synthesized by sonochemical route using (bis(salicylate)copper(II)) as a new copper precursor. The effects of different parameters such as sulphur source, solvent, power of irradiation and reaction time on the morphology of the products were investigated. Nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL) and Fourier transform infrared (FT–IR) spectroscopy. CuInS2 nanostructures paste was prepared by doctor’s blade technique on the transparent conductive oxide (TCO). The fill factor (FF), open circuit voltage (Voc), and short circuit current (Isc) were obtained by I–V characterization
