A new counter electrode which makes use of reduced graphene oxide (rGO), poly (3,4-ethylenedioxythiophene) (PEDOT) and aluminium oxide (Al2O3) was developed to enhance the performance of dye-sensitized solar cell (DSSC) device in replacing platinum as a counter electrode. PEDOT/rGO-Al2O3 was fabricated through the deposition of rGO/Al2O3 on indium tin oxide (ITO) glass by cyclic voltammetry followed by the deposition of PEDOT via chronoamperometry. The morphology of PEDOT/rGO-Al2O3 showed the combination of the wrinkled paper-like structure of rGO and coral-like morphology of PEDOT with nanoparticles of alumina, which gave the positive synergistic effects of the counter electrode to increase the performance of the DSSC. The electrochemical analyses indicated that PEDOT/rGO-Al2O3 exhibited a good electrocatalytic activity to act as a counter electrode in DSSC compared to PEDOT-rGO, PEDOT and rGO. The PEDOT/rGO-Al2O3 achieved power conversion efficiency (PCE) of 2.15%, which is higher compared to PEDOT-rGO (1.00%), PEDOT (0.69%) and rGO (0.09%).
