Description
Summary:In this study, a unique approach was developed to synthesize 1-D core-shell nanofibers ofcarbon nanotubes(CNTs) andTiO2 using combination of coaxial electrospinning and sol-gel technique. Diameters of thefabricatedcore-shell single wall carbon nanotube-TiO2 (SWCNT-TiO2) and multi wallcarbonnanotube-TiO2 (MWCNT-TiO2) nano-composite fibers werebetween 50-100nm. Energy dispersive spectroscopy(EDS) andX-ray photonspectroscopy(XPS) were applied to confirm encapsulation of carbon nanotube(CNT) in thecore-shell structure. Electron transport properties of both SWCNT-TiO2 andMWCNT-TiO2 in the Dye-sensitized solar cells(DSSCs) werestudied for the first time. It was found that SWCNT-TiO2 based DSSC provided higher shortcircuit current relative to MWCNT-TiO2, which was explained by I-V and bodeplots. These findings were further illustrated by semi-conductive properties of SWCNT.
