Paper Abstract

Tin sulfide (SnS) is one of promising candidate materials for low-cost thin film solar cells because of its high absorption coefficient and suitable band-gap. The aim of this paper is to study the properties of doped-SnS thin films prepared by vacuum evaporation. Sb2O3 was used as the doping source (the weight ratio of Sb2O3 to SnS in the range from 0.1% to 0.8%). And then the Sb2O3-doped SnS thin films were annealed in the hydrogen atmosphere at different temperatures and times. The structure of all the samples was characterized by X-ray diffraction (XRD). The electrical properties of SnS thin films were investigated as well. From the results, the optimum doping content of Sb2O3 was 0.2% in weight, and the resistivity of the doped-SnS film was 42Ω•cm while that of the pure-SnS film was 99Ω•cm. In addition, the film resistivity of Sb2O3-doped SnS film decreased to 24Ω•cm with the best annealing conditions of 400°C and 3 hours.
