A Deep Survey upon the Synthesis of AuS Nanostructures

In this research, the dendritic gold(I) sulfide nanostructures were successfully synthesized by a simple hydrothermal route. The effect of temperature, and reaction time, on the morphology and particle dimension was also investigated. Thus, the efficiency of synthesized gold sulfide nanostructures in thin-film solar cells was evaluated. The results indicated very well that the particle dimension and morphology have effect on solar cells efficiency and dendritic gold sulfide nano- structures have higher efficiency compared to spherical and rod-like gold sulfide nanostructures. Moreover, depositing of dendritic gold sulfide upon gold sulfide nanoparticles led to obtaining ۳.۲۸% cell efficiency that in comparison with sole dendritic nanostructures and sole nanoparticles (۱.۸۹%), efficiency improvements of ۴۸ and ۸۵% were, respectively, obtained.
