The Impact of PDDA in CNT Counter Electrode on the Conversion Efficiency of DSSC

Yoshiki Kurokawa, Dang Trang Nguyen, and Kozo Taguchi
Abstract—Dye-Sensitized Solar Cell (DSSC) is one of the equipment to convert sunlight into electricity. DSSC consists of anode electrode, titanium oxide ( ) thin film, sensitizer dye, electrolyte and cathode electrode (CE). In general, platinum (Pt) is usually used for CE. This paper studied the fabrication of CE using carbon nanotube (CNT) and CNT mixed with Poly (diallyl dimethylammonium chloride) (PDDA) (CNT/PDDA) as the substitution for Pt electrode. For the fabrication process, Electrophoresis Deposition (EPD) method was employed. CNT electrode was dried at room temperature at 25 oC or annealed at 400 oC for 1 hour, and CNT/PDDA CE was dried at room temperature at 25 oC. The thickness of CE we fabricated was around 15 . We adapted MK2 dye which was an organic dye for DSSC. Experimental results showed that the conversion efficiency of the DSSC in the case of CNT/PDDA CE (4.12%) was higher than that of the case of dried CNT electrode (2.78%) and annealed CNT electrode (3.49%) under the 1 sun illumination (100 ⁄ ). From this experiment results, PDDA has improved CE ability. In addition, CNT/PDDA CE do not need annealing process, so enabling flexible DSSC.

Index Terms—Dye sensitized-solar cell, carbon nanotube, poly (diallyl dimethylammonium chloride), organic dye mk2, no annealing, flexible.
