To improve the efficiency of dye sensitized solar cell (DSSC), high conductivity and porosity are required for counter electrode. In this study, polypyrrole (Ppy) was synthesized by oxidative polymerization using DEHSNa[di(2-ethylhexyl) sulfosuccinate sodium salt], DBSA[dodecylbenzenesulfonic acid], NSA[2-naphthalenesulfonic acid] as dopanst, respectively. To check the possibility of Ppy to apply DSSC as a counter electrode, electrical conductivity was measured using 4-probe method and porosity was measured by SEM and AFM. And current density of the I3- / I- redox reaction peak for the Ppy electrode was measured using cyclic voltametry. From the results, the performance of Ppy as a counter electrode in DSSC will be discussed. |
