Abstract: Pyrrole (Py) polymerized on multiwalled carbon nanotube@reduced graphene nanoribbon (MWCNT@rGNR) was reported as an efficient counter electrode (CE) for dye-sensitized solar cell (DSSC). Field-emission scanning electron microscopy (SEM) showed the microstructural detail of PPy/MWCNT@rGNR composite with the dense and flat pristine PPy film deposited on graphene sheet covering on a MWCNT and Raman spectroscopy were used to further confirm the formation of reduced graphene nanosheets and the degree of defect on the surface of PPy/MWCNT@rGNR composite, respectively. Cyclic voltammetry (CV) was used to study the electrocatalytic abilities of the films of MWCNT@GONR, MWCNT@rGNR, PPy, and PPy/MWCNT@rGNR. The CV measurement revealed that resultant composites exhibited a superior catalytic performance for tri-iodide reduction in the order of PPy/MWCNT@rGNR > MWCNT@rGNR > MWCNT@GONR> PPy. The efficiency of a solar cell with PPy/MWCNT@rGNR was comparable with platinized CE. Such excellent electrocatalytic ability for the reduction of I3- ions can be attributed to the fact that PPy has high conductivity and superior electrocatalytic activity as well as MWCNT@rGNR has high electron transfer, surface roughness, and surface area to promote the reduction and regeneration of I3- ion.
