Facile synthesis of SnS nanostructures with different morphologies for supercapacitor and dye-sensitized solar cell applications

In this paper, tin Sulfide (SnS) nanoparticles are synthesized with three different solvents through hydrothermal method and characterized by using X-ray diffraction, scanning electron microscopy, UV-DRS spectroscopy, Fourier transform infrared energy-dispersive spectrum, supercapacitor, photovoltaic performance. XRD patterns indicate that the prepared SnS exist in orthorhombic phase. The SEM analysis clearly picturizes morphological changes solvents. spectrum gives direct energy band gap which lies between 1.0 2.0 eV. FT-IR explains various functional groups present nanoparticles. counter electrodes (CEs) showed good electrocatalytic activity redox reaction of I−/I3−. efficiency sulfide ethanol (SnS-e), acetone (SnS-a), methanol (SnS-m) 9.99%, 9.90%, 9.86% Dye-sensitized solar cells (DSSC) than platinum electrode is 9.80%. specific capacitance 284 F/g obtained for SnS-e at a current density 5 A/g an 216 Wh/kg corresponding to power value 1.6 KWh/kg proves possesses better capacitive performance SnS-a SnS-m electrodes, respectively.
