The effect of anthocyanin extracted from Heritiera borneensis (Mengkulang) on dye sensitized solar cell (DSSC)

Dye-sensitized solar cells (DSSC) are the third and latest generation of solar cells that have promising potential in the future. The objective of the study is to investigate the effect of anthocyanin on dye-sensitized solar cells using (Heritiera borneensis) sensitizer by current voltage measurement. In wood based industry likes sawmill and plywood, have generated 1.47 million m3 of waste in high value added products from wood waste. Heritiera borneensis (Mengkulang) wastes were ground to size 0.1 to 0.4 mm and solvent extracted with nitric and citric acid for 24 hours to investigate its dyes’ potential as a dye sensitizer for dye sensitizer solar cell (DSSC). The colour dyes produced from nitric and citric acid were investigate with using four type of test which were Fourier Transform Infrared Spectroscopy (FTIR), Incident Photon-Current Efficiency (IPCE), Cyclic Voltammetry (CV) and Current-Voltage Measurement (I-V). The sudy found that dyes from these solvents were dominant with carboxyl and hydroxyl groups which important for transferring the photon from the sun to the solar cells. The Mengkulang dyes had a conversion efficiency (ƞ) of 0.154%, with open circuit voltage (Voc) of 0.51V, short circuit current density (Isc) of 0.36 mA cm-2 and fill factor (ff) of 84, under the irradiance of 1000 Wm-2. This indicated that the Mengkulang dyes had a high potential as a sensitizer of DSSC.
