Theoretical design and experimental synthesis of counter electrode for dye-sensitized solar cells: Amino-functionalized graphene简
For some specific catalytic reaction, how to construct active sites on two dimensional materials is of great scientific significance. Dye-sensitized solar cells(DSCs) can be viewed as one representative photovoltaics because in which liquid electrolyte with triiodide/iodide(I3-/I-) as redox couples are involved. In this study, amino-functionalized graphene(AFG) has been designed according to theoretically analyzing iodine reduction reaction(IRR) processes and rationally screening the volcanic plot. Then, such AFG has been successfully synthesized by a simple hydrothermal method and shows high electrocatalytic activity towards IRR when serving as counter electrode in DSCs. Finally, a high conversion efficiency of 7.39% by AFG-based DSCs was obtained, which is close to that using Pt as counter electrode.
