Polydispersed-size nanocrystallite titanium dioxide (TiO2) with a large surface area is fabricated by nozzle-less electrospraying using titanium isopropoxide (TIP)/polyvinylpyrrolidone (PVP) ethanol solution. The polydispersed TiO2 nanoparticles are applied to dye sensitized solar cells as a novel scattering layer, which balances both dye loading and light trapping. An optimal high efficiency of 8.71% is achieved with the polydispersed-size TiO2 nanoparticles as the scattering layer when compared with an efficiency of 7.17% obtained for the photoanode with the traditional scattering layer made of 200 nm monodispersed TiO2 nanoparticles, which represents a 22% increase.
