Speed up dye-sensitized solar cell fabrication by rapid dye solution droplets bombardment

In this work, we show that by high-speed dye solution droplet bombardments, TiO2 dye adsorption time in dye-sensitized solar cell fabrication reduces from hours to minutes. While 24-hr dye solution bath gives cells with the efficiency of 4.62%, 9 min bombarding time in 1500 rpm spinning disc system and 8.3 min bombarding time in 2000 rpm spinning disc system give cells with efficiencies of 4.68% and 4.58%, respectively. The proposed method is ideal for rapid DSSC fabrication.
