This study examined and described the optical photovoltaic (PV) characterizations of Fruit Areca catechu (pinang) as a new type organic sensitizer. Recent reports stated that including chenodeoxycholic acid (CDCA) in dye improves performance dye-sensitized solar cells (DSSCs). The effectiveness PV was investigated by applying it DSSC. absorption spectra indicated natural dyes with CDCA has an excellent stabilizing ability. Fourier-transform infrared existence carboxylic hydroxyl functional groups naturally extracted dye. These were responsible for rapid electron transfer strong electronic linkages interactions within TiO2 surface. In this study, photoluminescence analysis showed narrowing bandgap, incorporating co-adsorbent could generate significant photocurrent. overall power conversion efficiency enhanced 4.6%. Moreover, cell reached up to 0.076% after adding 1.5 mM without optimizing sensitization time. Results demonstrated present contributes toward improvement DSSC through efficient injection.
