Incorporation of ${rm TiO}_{2}$ nanoparticles into ${rm SnO}_{2}$ nanofibers as photoanode in dye-sensitized solar cells improved the cell efficiency from 4.63% to 6.17%. The addition of ${rm TiO}_{2}$ nanoparticles increased the surface area of the photoanode that led to the enhancement in the dye attachment. In addition, the incorporation of ${rm TiO}_{2}$ nanoparticles helped in the reduction of the recombination of electrons in the photoanode with the electrolyte resulting in the increase in the open circuit voltage $(V_{rm{oc}})$ and fill factor.
