Vertically aligned CoS prismatic nanorods were synthesized on transparent conductive fluorine-doped tin oxide (FTO) substrates by a two-step method. First, vertically aligned Co3O4 prismatic nanorod arrays were prepared by a rapid microwave irradiation method. Second, Co3O4 were converted to CoS nanorods by solution-based ion exchange reaction (IER). The dye-sensitized solar cell (DSSC) using CoS prismatic nanorods arrays as the counter electrode (CE) achieves a power conversion efficiency of 6.06%, which is comparable with the cells based on Pt-CE (6.45%).
