Abstract
In this study, we report on the synthesis of Sb2S3 nanorods by using a hot-injection process in short processing time (1 h). Synthesized Sb2S3 nanorods are used as an electrochemical catalyst (counter electrode) for triiodide reduction in dye-sensitized solar cells (DSSCs). X-ray diffraction and field emission gun-transmission electron microscopy (FEG-TEM) analysis confirm the crystallinity of synthesized nanorods. The size and shape of synthesized materials are measured with the help of FEG-TEM analysis. Electrocatalytic activity study of Sb2S3 nanorods demonstrates the suitability of this material as an alternative electrochemical catalyst for DSSCs. The photoconversion efficiency of DSSCs fabricated using Sb2S3 as counter electrodes is found to be 4.1%.
