Growth of well graphitized MWCNTs over novel 3D cubic bimetallic KIT-6 towards the development of an efficient counter electrode for dye-sensitized solar cells

- Graphitized MWCNTs exhibiting energy conversion efficiency of 9.56%, higher than the Pt.
- The CNTs based counter electrode performs better than Pt.
- MWCNTs produce Rct of 2.99 Ω cm2 lower than Pt electrode (3.57 Ω cm2).
- MWCNTs counter electrode have better catalytic properties for I3− reduction.
- MWCNTs have been succesfully synthesized over 3D bimetallic Fe-Co-KIT-6.
