Abstract:In this study we demonstrate the synthesis of quaternary semiconductor nanocrystals of stannite Cu 2 FeSnS 4 /rhodostannite Cu 2 FeSn 3 S 8 (CFTS) via mechanochemical route using Cu, Fe, Sn and S elements as precursors in one-pot experiments. Methods of X-ray diffraction (XRD), nitrogen adsorption, high-resolution transmission electron microscopy (HRTEM), scanning transmission electron microscopy (STEM), energy-dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS) were applied to characterize properties of the unique nanostructures. Mechanochemical route of synthesis induced new phenomena like explosive character of reaction, where three stages could be identified and the formation of nanostructures 5-10 nm in size. By using XPS method, Cu(I), Fe(II), Sn(IV) and S(-II) species were identified on the surface of CFTS. The value of optical band gap 1.27 eV is optimal for semiconductors applicable as absorbers in solar cells. The significant photocatalytic activity of the CFTS nanocrystals was also evidenced. The obtained results confirm the excellent properties of the quaternary semiconductor nanocrystals synthesized from earth-abundant elements.

The Bi2O3 thin films were prepared onto glass substrates by spray pyrolysis method. The Bi2O3 thin films optimized at 320 °C spray pyrolysis temperature. The crystal structure, crystallite size, and surface morphology of Bi2O3 thin films were studied by X‐ray diffraction (XRD) and scanning electron microscopy (SEM) techniques, respectively. The X‐ray diffraction pattern of Bi2O3 thin films show polycrystalline in nature. The SEM images show porous morphology of Bi2O3 thin films. The optical absorption spectra of films were examined in order to study their band gap energy. The optical study shows a direct band gap of 2.90 eV for Bi2O3 films.

“…The CFTS nanoparticles reveal slight agglomeration with irregular sphere like particle average size from 10-30 nm, which agrees with the XRD data. This slight agglomeration could be attributed to an increase in surface energy with decrease in size [24]. This kind of sphere like morphology enhances photon absorption and hence finds use in photovoltaic applications.…”

Quaternary semiconductor Cu 2 FeSnS 4 (CFTS) nanoparticle powder have been prepared by a simple chemical technique. The synthesized CFTS nanoparticles have been characterized via powder XRD analysis, Raman spectra, FE-SEM-EDS, UV-Visible absorption spectroscopy, thermal analysis and electrochemical characterization. Powder XRD and Raman spectroscopy confirm the phase and structure of the prepared nanoparticles. The optical absorption studies reveal that the CFTS nanoparticles have a direct optimal band gap in the range from 1.32 to 1.5 eV, which indicates that these nanoparticles are potential absorber materials for thin-film photovoltaic application. The synthesized CFTS nanoparticles were transformed to the ink form and the obtained nanoparticle ink coated on a FTO conducting substrate (surface resistivity-13 Ω sq −1 ). The catalytic activity of the substrate was analyzed by electrochemical impedance spectroscopy (EIS) and cyclic voltammogram (CV) curves. The appropriate optical band gap and stable electrical properties indicate that Cu 2 FeSnS 4 Nanoparticles are potential materials for thin-film photovoltaic application.
