In this study, polypyrrole (Ppy) was synthesized by oxidative polymerization using NSA [2-naphthalenesulfonic acid] as a dopant. To check the possibility of polypyrrole for application to DSSC as a counter electrode, electrical conductivity was measured using 4-probe method and porosity was measured by SEM. Current density of the I3- / I- redox reaction peak for the Ppy electrode was measured using cyclic voltametry. DSSC with the structure ofFTO / TiO2 / electrolyte / Ppy / FTO was fabricated and its efficiency was obtained from I-V curves. From the results, the performance of Ppy as a counter electrode in DSSC will be discussed. |
