A counter electrode is one of the crucial components in dye-sensitized solar cell (DSSC), where platinum, carbon composite, and poly(3,4-dioxythiophene)-poly(styrene sulfonate) or PEDOT:PSS are among the most widely used materials. In terms of configuration, DSSC is typically constructed in two ways: sandwich and monolithic. However, the DSSC performance associated with the selection of both counter electrodes and configuration has received little attention to date. This study aims to study the effect of counter electrode materials on DSSC performance by analyzing their electrical and electrochemical properties from their configuration standpoint. First, the physical properties of the counter electrodes materials were analyzed using scanning electron microscopy (SEM), followed by four-point probes, electrochemical impedance spectroscopy (EIS), incident photon-to-current conversion efficiency (IPCE), and current density-voltage (J-V) characterization. Among all variations, our results show that the sandwich-type DSSC with PEDOT: PSS counter electrode generated the best performance with a power conversion efficiency of 5.40%, which was primarily attributed to the high conductivity (3210 S/cm) and low charge transfer resistance (RCE 53 Ω). It was also found that the electron transfer pathways that are determined by the cell configuration also had a significant impact on the cell performance.
