文摘

Carbon nanotubes (CNT), core鈥搒heath CNT/reduced graphene oxide nanoribbon (RGONR), CNT/RGO composite, and RGO fibers have been compared as counter electrodes to fabricate novel dye-sensitized solar cells. For the I^{鈥?/sup>/I₃鈥?/sup> electrolyte, the core鈥搒heath CNT/RGONR fiber shows the best catalytic activity, which in turn produces the highest energy conversion efficiency of 5.64%. In contrast, for the organic T鈥?/sup>/T₂ electrolyte, the highest energy conversion efficiency has been produced from the CNT fiber counter electrode with the maximal value of 4.78%. The different electrocatalytic activities among these four carbon nanostructured fibers on the two typical electrolytes of I鈥?/sup>/I₃鈥?/sup> and T鈥?/sup>/T₂ have been carefully investigated in this work.}
