Abstract

Pure Sb2S3 without oxide impurities was formed by thermal decomposition of Sb(thioacetamide: TA)2Cl3 precursor. From the analysis of thermal properties of Sb(TA)2Cl3, 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/cm2 of short circuit current density (Jsc), 0.616 V of open circuit voltage (Voc), 45.9% of fill factor (F.F), and overall power conversion efficiency (η) of 2.3% at 1 sun condition.
