Abstract
In this research, we fabricate SnS films using a low-cost spray pyrolysis technique. Several parameters such as grain size, textural coefficient, Sn concentration, root mean square (RMS), optical band gap, Urbach and dispersion energy are determined by the mean of X-ray diffraction pattern, UV-Vis measurements, surface morphology observation by scanning electron microscopy (SEM)-energy dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), selective area electron diffraction (SAED) and atomic force microscopy (AFM). Furthermore, SnS thin films exhibit a polycrystalline structure having a low grain size of 6.1 nm along principal (111) orientation. The optical band gap is around 1.9 eV and Urbach energy is of 740 meV. The dielectric parameters of chalcogenide SnS thin film are varying with photon energy within ultraviolet-visible-infrared (Uv-Vis-IR) bands. Besides, the single oscillator E0 and Ed energies are found to be 2.03 and 3.28 eV, respectively, using the Wemple and DiDomenico (WDD) model.Electrical measurements of SnS thin films deposited onto Indium Tin Oxide (ITO) substrate are accomplished and current-voltage (I–V) characteristics of SnO2 / SnS/ITO, are shaped in dark and room temperature conditions. Photovoltaic parameters like open circuit voltage (Voc ), short circuit current (Isc ), fill factor (FF) and power conversion efficiency (η) values are determined and SnO2 / SnS/ITO junction records the highest values.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
