Pure Sb2S3 without oxide impurities was formed by thermal decomposition of Sb(thioacetamide: TA)(2)Cl-3 precursor. From the analysis of thermal properties of Sb(TA)(2)Cl-3, we developed a spin-coating and heat-treatment process to form pure Sb2S3 thin-films with controllable thickness due to the formation of insoluble Sb2S3 by heat-treatment. Through the spin-coating and heat-treatment process, we could fabricate oxide-free Sb2S3 planar type sensitized solar cell with 8.12 mA/cm(2) of short circuit current density (J(sc)), 0.616 V of open circuit voltage (V-oc), 45.9% of fill factor (F.F), and overall power conversion efficiency (eta) of 2.3% at 1 sun condition.
