Tin sulfide films as promising materials for solar assisted catalysis and solar cells: Investigation of electronic structural properties

The narrow band gap of SnS enables the utilization of solar energy and makes it a potential candidate for the low-cost solar energy conversion material and the efficient visible- light-driven photocatalyst. The sustainable manufacturing of solar devices is feasible if tin sulfide materials are used as cheap, nonstrategic and ubiquitous in nature, leading to the development of environmentally safe devices. A wide application of tin sulfides includes: solar collectors, photodetectors in photovoltaic solar energy devices, photocatalysts in advanced oxidation processes, as well as promising alternative for anode materials to replace commercial carbonaceous electrodes (graphite) in lithium-ion and sodium-ion batteries due to their high capacities. In this work, environment friendly and facile approach has been introduced for synthesis of the passive sulfide films on tin, employing non–toxic and low–cost materials. The tin sulfide film, formed by potentiostatic anodic polarization on tin in aqueous electrolyte solution, containing sulfide ions, was investigated using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and diffuse reflectance spectroscopy (DRS). The electronic structure of the tin sulfide film was discussed on the basis of the band structure model of the surface film, the potential distribution across the film and at the metal|film|electrolyte interfaces as well as the availability of free charge carriers on the electrode|solution interface. The electronic structure of the tin sulfide film influences its susceptibility to the oxidative as well as to the reductive solid–state decomposition. The results presented in this work enable a better insight into the electronic structure semiconducting properties of the tin sulfide film that are essential to predict its suitability for optoelectronic and photovoltaic device applications.
