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 1Sun illumination. Under reduced light intensity (0.25Sun), TiO2-NF and TiO2-NF/SWCNT-based DSSCs reached PCE values of up to 3.7% and 6.6%, respectively.
