Abstract
In the present work, a pioneering attempt has been made for the rapid synthesis of Cu2ZnSnS4 (CZTS) microspheres by the microwave-assisted solution method. X-ray diffraction (XRD) and Raman spectroscopy confirmed the formation of single phase CZTS with tetragonal crystal structure. Scanning electron microscope (SEM) and transmission electron microscope (TEM) showed the formation of sphere-like CZTS microparticles. Optical absorption studies revealed that CZTS microparticles have an optical band gap of 1.76eV, which is optimal for photovoltaic applications. The simplicity, rapidity, and commercial feasibility of the current synthesis strategy would be beneficial for the low-cost and large-scale industrial production of CZTS.
