Abstract :
Incorporation of TiO2 nanoparticles into SnO2 nanofibers as photoanode in dye-sensitized solar cells improved the cell efficiency from 4.63% to 6.17%. The addition of TiO2 nanoparticles increased the surface area of the photoanode that led to the enhancement in the dye attachment. In addition, the incorporation of TiO2 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 (Voc) and fill factor.
