文摘

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%.
