Flower-like Cu₂FeSnS₄ particles synthesized by microwave irradiation method

摘要

Cu2FeSnS4 particles were prepared by using a microwave irradiation method. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and UV-vis-NIR absorbance spectroscopy measurements show that the Cu2FeSnS4 products exhibit flow-liked particles with spherical structure and idea band gap (Eg=1.52eV), indicating a potential candidate for application as absorber layer in thin film solar cells.
