Abstract

A light-scattering layer fabricated from electrospun titanium dioxide nanofibers (TiO2-NFs) and single-walled carbon nanotubes (SWCNTs) formed a fiber-based photoanode. The nanocomposite scattering layer had a lawn-like structure and integration of carbon nanotubes into the NF photoanodes increased the power conversion efficiency from 2.9 % to 4.8 % under 1 Sun illumination. Under reduced light intensity (0.25 Sun), TiO2-NF and TiO2-NF/SWCNT-based DSSCs reached PCE values of up to 3.7 % and 6.6 %, respectively.
