Formation of artificial pores in nano-TiO(2) photo-electrode films using acetylene-black for high-efficiency, dye-sensitized solar cells

Acetylene-black paste without a light scattering layer was applied to meso-porous TiO(2) photo-electrode films with a crystalline framework, a low residual carbon, and a tunable morphological pore size. The thermal-treated TiO(2) photo-electrode films had an increased acetylene-black concentration w...

Sumario:Acetylene-black paste without a light scattering layer was applied to meso-porous TiO(2) photo-electrode films with a crystalline framework, a low residual carbon, and a tunable morphological pore size. The thermal-treated TiO(2) photo-electrode films had an increased acetylene-black concentration with an increase in artificial pores and a decrease in residual carbon. The performance of dye-sensitized solar cells (DSSCs) was enhanced by the use of the TiO(2) photo-anode pastes at various acetylene-black concentrations. The photo-conversion efficiency of the DSSCs using TiO(2) photo-electrode films with 1.5 wt% acetylene-black was enhanced from 7.98 (no acetylene-black) to 9.75% without the integration of a light- scattering layer.
