SnS: Ag thin films were deposited on ITO glasses by pulse electro-deposition. By studying the effect of duty cycle on the properties of SnS: Ag thin films, the optimum off-time(toff) is obtained to be 5 s,namely, the optimal duty cycle is about 67%. The primary phase of SnS: Ag films deposited on optimum parameters condition is SnS compound with good crystallization, and the films prefer to grow towards (111)plane. The films are dense, smooth and uniform with good microstructure, and the grains in the films are densely packed together, and their direct bandgap is about 1.40 eV.In addition, the bandgap of the films first rises and then drops with the increase of the duty cycle.
