Abstract

Effects of incorporation of acid-treated single-wall carbon nanotubes (a-SWCNs) in TiO2 film and of anchorage of dye-linked,a-SWCNs(hereafterdye-SWCNs)to theTiO2/electrolyte interface on photocurrentvoltage characteristics of dye-sensitized solar cells were studied. Compared with an unmodified cell, the modified cell with the a-SWCNs in TiO2 film showed a 25% increase in short-circuit photocurrent (Jsc). The Jsc increase is correlated with improved connectivity between the a-SWCNs and the TiO2 particles and with enhanced light scattering by TiO2 clusters formed in the presence of the a-SWCNs. In the case of anchoring dye-SWCNs to the TiO2/electrolyte interface, the open-circuit voltage (Voc) increased by as much as 0.1 V, possibly due to the basicity of the TiO2 surface fromNHgroups of ethylenediamine moieties of the anchored dye-SWCNs.
