Dye extracted from Costus woodsonii leave as a natural sensitizer for dye-sensitized solar cell / M.Z. Najihah and Tan Winie
Current work employs dye extracted from leaves of Costus woodsonii as a new sensitizer for dyesensitized solar cells (DSSCs). The leave was extracted in three different solvents namely ethanol, methanol, and acetone. Extraction of leaves was carried out by the freezing method. DSSCs with the configu...

DSSCs with the configuration of TiO2/dye/electrolyte/Pt were assembled. The dyes in DSSCs were Costus woodsonii leaves extracted in methanol, ethanol, and acetone.
