Abstract/Summary

Continuous improvements to the performance of dye-sensitized solar cells (DSSCs) are sought after and alternative to the expensive platinum in the counter electrode is a major component to be considered. This study investigated the effect of applying molybdenum, cobalt and multi-walled carbon nanotubes (MWCNT) nano-powders to the counter electrode and MWCNT onto the photo anode at 1:1 wt.% with TiO2 and as a CNT stand-alone catalyst in the anode. CNT saturating the catalyst films in photo anode was found to not produce power. With TiO2 in the anode, DSSCs with electrodes having tandems of Molybdenum-CNT and Cobalt-CNT at 1:1 wt.% were found to give highest efficiency, about 10 times than that of the platinum-based counter electrodes.
