Description |
High quality MWCNT material based counter electrodes for dye-sensitized solar cells (DSSCs) were
fabricated using a novel route and their power-conversion efficiency was studied. Transition metals such
as Fe, Ni, V, Mn, Cr, Mo, Ru and Pd loaded on Co-SBA-15 molecular sieves were synthesized and tested
for the formation of MWCNTs at different temperatures (700–1000 �C) using a chemical vapour
deposition (CVD) method. This result showed that Fe/Co-SBA-15 and Ru/Co-SBA-15 systems are highly
suitable sources as catalysts for the growth of MWCNTs compared to other bimetallic systems. TEM and
Raman spectroscopy revealed that the synthesized MWCNTs were of high quality and well-graphitized.
The MWCNTs were applied to the counter electrode of dye-sensitized solar cells (DSSCs). Cyclic
voltammetry measurements proved that the catalytic activity of the MWCNT coated electrode towards
I3
� reduction was significantly higher than that of the Pt coated electrode. Electrochemical impedance
measurement of the symmetric cell revealed that the charge transfer resistance of the MWCNT coated
electrode was less than that of the Pt coated electrode. Due to the low charge transfer resistance of the
synthesized MWCNTs, the DSSCs with MWCNTs as counter electrode gave better photoelectric
performance compared to DSSCs equipped with a conventional Pt counter electrode
