Abstract
Cu2FeSnSe4 (CFTSe) microparticles were successfully synthesized by an atmospheric pressure liquid reflux method in triethylenetetramine for the first time. The structure of prepared CFTSe microparticles was characterized by X-ray diffraction (XRD) and Raman spectra. The results clearly showed that the synthesized CFTSe microparticles had a single-phase stannite structure. The morphology and chemical composition of CFTSe microparticles were confirmed by scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). The ratio of Cu/Fe/Sn/Se was about 2.00:0.88:1.02:4.29. Moreover, the prepared products with the size of 0.4-0.6 µm were spherical. Ultraviolet-visible spectrophotometry (UV-vis) analysis showed that the energy band gap was 1.47 eV. It indicated that the synthesized CFTSe microparticles were suitable for solar cell applications as absorption material.
