Electrospun coaxial titanium dioxide/carbon nanofibers for use in anodes of dye-sensitized solar cells

- Coaxial TiO2/carbon nanofibers (TCNFs) were fabricated by coaxial electrospinning.
- After carbonization, TCNFs were formed with anatase TiO2 shell and carbon core.
- The carbon core improved electron transport and minimized charge recombination.
- The performance of TCNF-based DSSC device shows a high η value, 7.5%.
