[ABSTRACT ]

The optimization of dye in dye-sensitized solar cells (DSSCs) can improve their electrochemical performance. Therefore, this study aimed to investigate the effect of Dyenamo red dye (DN-F05) with the addition of chenodeoxycholic acid (CDCA) to inhibit the aggregation of molecules in the dye and suppress charge recombination. The results showed that the highest DSSC performance was achieved with a combination of 0.5 mM DN-F05 and 7.5 mM CDCA, with a Jsc value of 8.35 mA.cm-2, Voc 0.689 volts, and efficiency 2.988% compared to 1.974% without CDCA. Furthermore, DSSC efficiency increased slightly after 50 days, showing good stability at ambient temperature.
