Dye-sensitized solar cells with TiO2 nano-particles on TiO2 nano-tube-grown Ti substrates

In the present work, dye-sensitized solar cells (DSSCs) were prepared with TiO2 nano-particles on TiO2 nano-tube-grown Ti substrates. A slow electron recombination and a light scattering effect might have simultaneously contributed to the DSSC performance and resulted in improvements in the short-circuit current (J(sc)) and in the conversion efficiency.
