To improve the efficiency of dye sensitized solar cell (DSSC), high conductivity and porosity are required for counter electrode. In this study, polyaniline (PANI) was synthesized by oxidative polymerization using camphorsulfonic acid and m-cresol as promary and secondary dopant, respectively. To check the possibility of PANI 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 PANI electrode was measured using cyclic voltametry. From the results, the performance of PANI as a counter electrode in DSSC will be discussed. |
