This paper presents research on the effect of counter electrode materials on the performance of dye-sensitized solar cells (DSSCs). The counter electrode materials were varied in the form of platinum, carbon, and poly (3,4-ethylene dioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS), all of which were screen printed on top of a transparent conductive substrate. The morphology of the counter electrodes was characterized using scanning electron microscopy (SEM) while the electrical properties were characterized using the four-point probe, incident photon-to-current efficiency (IPCE), and current-voltage characterization. The measurement results showed that PEDOT:PSS had a smoother surface structure and lower sheet resistance (3.15 Ω/sq) than platinum and carbon. Counter electrode with PEDOT:PSS generated the highest DSSC performance with IPCE 55 %, JSC 7.95 mA/cm², VOC 0.66 V, FF 0.52, Pmax 0.68 mW, and photoconversion efficiency of 5.40 %. The high DSSC performance shown by the PEDOT:PSS counter electrode was attributed by the high conductivity that was associated with the electron transfer process from counter electrode to electrolyte, which consequently increases the regeneration of electrons within the electrolyte and dye.
