Synthesis and Characterization of Copper Indium Sulfide Microsphere and its Application in Low-Cost Solar Cell

Abstract

CuInS2 microsphere was synthesized by Ultrasonic method in propylene glycol, as solvent, and copper complex, indium chloride and thioacetamde (TAA) as precursors. Optimum conditions such as reaction time, solvent type, sulfur source, and ultrasonic power were determined. Then thin film of CuInS2 was prepared and its application in solar cells was investigated. To investigate solar cell application of CuInS2 in the present experiment, at first CuInS2 paste was prepared from nanoparticle and then thin film prepared by doctor balding. I–V curves offer key parameters including short-circuit current (ISC) and the opencircuit voltage (VOC). Another important parameter for solar cells is fill factor (FF). A series of analysis including X-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL) spectroscopy were performed to characterize the CusInS2 microsphere. The optical band gap of CuInS2 microsphere was estimated to be 2.28 eV. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/34995
