Electrically conductive polymers have been widely studied for potential use as counter electrodes (CEs) for DSSCs. Among them, PANI has been intensively studied as CEs for DSSCs due to its ease of synthesis, low cost, reversible redox property, tunable conductivity, good environmental stability. In this study, we investigated the feasibility of PANI nanorods as a counter electrode for DSSCs application. PANI nanorods were synthesized by rapidly mixing reaction using APS solution as a initiator. The synthesized PANI nanorods had a uniform diameter of ~50nm. From the FT-IR analysis, it could be concluded that the PANI nanorods were successfully synthesized and its electrical conductivity was ~11S/cm. The morphology of the resultants was observed using TEM. Photovoltaic performances of the PANI based DSSCs were characterized by photocurrent density-voltage and IPCE measurements.
