Abstract:

Dye-sensitized solar cells (DSSC) were fabricated using red Bougainvillea glabra 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. Dye-sensitized solar cells (DSSCs) from dye extract of pH 3.0 had the highest photocurrent density J of 3.72 mA/cm2 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 mA/cm2 and 2.27 mA/cm2, 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/cm2 for dye sensitizer pH of 1.23, 3.0 and 5.7 respectively.
