文摘
- •
3D hierarchical G/CNFs–Ni was developed as a novel counter-electrode nanomaterial for efficient DSCs.
- •
G/CNFs–Ni was synthesized by electrospinning G/PAN/Ni(AcAc)2 precursor nanofibers, followed by carbonization and activation.
- •
Graphene and Ni in CNF networks significantly increased the cells' stability and decreased the charge-transfer resistance.
- •
G/CNFs–Ni Possessed larger capacitance than that of Pt due to larger specific surface area, leading to higher efficiency.
