摘要
Typical DSSCs are composed of a fluorine-doped tin oxide(FTO) glass, a dyed coated TiO_2 anode, an electrolyte, and a counter electrode(CE). The function of CE is to catalyze the iodine/iodide(I~-/I_3~-) redox couple and complete the electric circuit in the DSSCs. Becuse Pt electrode can be decomposed to PtI_4 by I~-/I_3~- redox couple, thus resulting in the critical issues on the cell performance, long-term stability, and commercialization of DSSCs. Therefore, it is necessary to explore Pt-free CEs to facilitate the industrial development of DSSCs. The present work is to synthesis new substitude materials to instead of costly Pt electrode. Niobium-based bimetal oxides, Nb_2FeO_6 and Nb_2CoO_6, have been sucessfully synthesized by a simple chemical method. As a CE for DSSCs, power conversion efficiencies of 5.14% and 3.15% were achieved after preliminary evaluation of PV performance, in which new component systems, dye Y123, dye D35 and Cu eletrolyte have been employed. To detect the further characteristics, CV, Tafel, EIS etc. have been investigated. The results show that niobium-based bimental oxides exhibit considerable catalytic activity and stability.
