Solar cells with the structure ITO-PEDOT:PSS-Ag:SnS-Al were fabricated with the active layer of tin sulphide with silver nano-particles (Ag:SnS) grown by thermal co-evaporation. To understand the influence of the silver nanoparticles on the energy conversion process, various cells with varying active layer thicknesses were compared. Results showed that the Ag nanoparticles act as scattering centers, resulting in longer optical path lengths for incident light. This in turn results in more charge carriers being generated and thus enhances the efficiency of the structure as compared to the pristine ITO-PEDOT:PSS-SnS-Al structure. The plasmonic solar cells of SnS showed an improvement of more than 40%. The results are encouraging and suggests more concerted effort needs to be made on SnS.
