Abstract
The adsorption of the dye molecules onto TiO2 in a dye solution bath usually takes hours and is the rate-limiting step in rapid dye-sensitized solar cell (DSSC) fabrication. Here, we show that by high-speed dye solution droplet bombardments, TiO2 dye adsorption time reduces from hours to minutes. While 24-hr dye solution bath gives the cell with the efficiency of 4.62% (9 mm×9 mm), 9 min dye adsorption time in the 1500 rpm spinning disc system and 8.3 min dye adsorption time in the 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. © 2013 Elsevier B.V.
