摘要
Transition metal compounds(TMCs) are widely believed that have the similar electronic structures with Pt, which indicate that TMCs can behave Pt-like catalytic activity and could be used as counter electrodes(CEs) for dye-sensitized solar cells(DSSCs).Molybdenum(Mo)-based compounds were widely used as the CEs materials for DSSCs and get comparable power conversion efficiencies(PCEs) with Pt CE.Three kinds of Mo-based compounds(Bi@Mo_2C, C@Mo_2C and MoO_2) have been used to replace the Pt as CEs in DSSCs in this work.These catalysts all showed excellent catalytic activity for the reduction of I_3~- to I~-in the electrolyte, showed surprisingly high PCEs of 8.0%, 7.8% and 7.2%, respectively.Those PCEs are greater than the Pt electrode in I_3~-/I~-electrolyte system(6.3%), indicating a great potential for the three Mo-based compounds to replace the expensive Pt CE.Since D35 and Y123 sensitizers with the new Cu(Ⅱ/Ⅰ)(tmby) electrolyte have achieved satisfactory results in DSSCs.Then as-prepared molybdenum-based compounds will be further applied in new-system DSSCs with the new sensitizers and electrolyte and the anaerobic digestion(AD) in future.
