Abstract

Dye-sensitized solar cells DSSC were fabricated using red bougainvilleaglabra flower dye extracts as natural dye sensitizers at three dye pH values of 1.23, 3.0, and 5.7. Water was used as dye-extracting solvent. DSSCs from dye extract of pH 3.0 had the highest photocurrent density Jsc of 3.72 mA-cm and fill factor FF of 0.59. While the DSSCs from dye sensitizer pHs of 1.23 and 5.7 had Jsc of 1.13 and 2.27 mA-cm, and fill factors of 0.43 and 0.61, respectively. The maximum powers Pmax of the DSSCs were 0.50, 1.64, and 0.94 mW-cm for dye sensitizer pH of 1.2, 3.0, and 5.7, respectively.
