“…Thermodynamically, the most stable form is β-In 2 S 3 , which was reported to exhibit exceptional optoelectronic performances [18]. This β form has been widely considered for photocatalysis, photovoltaic systems, antibacterial activity [19][20][21][22], and also as a photosensor material. It has been reported that solar cell devices using β-In 2 S 3 as a buffer layer provide a fractional conversion value close to that of the standard cadmium sulfide (CdS) buffer layer (16.4%) [23].…”

Spray pyrolysis was used to deposit indium sulfide (In2S3) films, with or without silver doping. The films are polycrystalline, and the inclusion of Ag in the In2S3 structure leads to the formation of a solid solution, with the crystallite size of the order of tens of nanometers. In2S3 films exhibit a semiconductive behavior, and the incorporation of Ag leads to an increase of the charge carrier concentration, enhancing the electrical conductivity of the films. The small polaron hopping mechanism, deduced by the fittings according to the double Jonscher variation, explains the evolution of the direct current (dc) conductivity at high temperature of the Ag-doped indium sulfide. From impedance spectroscopy, it was found that the doped film presents dielectric relaxation, and Nyquist diagrams indicate the importance of the grain and the grain boundaries’ contributions to the transport phenomena. The physical characteristics of the films have an influence on the photocatalytic performance, achieving photodegradation efficiency above 80% (85.5% in the case of Ag doping), and on the antibacterial activity. The obtained results indicate that indium sulfide films are good candidates for environmental and biological applications, confirming a multifunctional nature.
