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.
