Abstract

A platinum/reduced graphene oxide (Pt-rGO) thin film was prepared and deposited on a fluorine-doped tin oxide (FTO) substrate using the doctor blade method and was annealed at 450 °C for 30 minutes. Thin films were used as counter electrode in a dye-sensitized solar cell (DSSC) with Pt-rGO ratios of 1:1, 1:2, and 2:1. Cyclic voltammetry showed that the Pt-rGO thin film with a ratio of 1:1 exhibits better electrocatalytic activity for I3-/I- redox reaction. The current-voltage curve (I-V) revealed that DSSC using the Pt-rGO CE thin film with a ratio of 1:1 has a power conversion efficiency (PCE) of 6.3% under AM 1.5 illumination of 100 mW cm−2 and this is higher than Pt (6.1%). The current density (Jsc) is 14.3 mA/cm−2, open circuit voltage (Voc) is 0.75 V, and fill factor (FF) is 58.98.
