Synthesis Dye Sensitized Solar Cells from Red Sandal Wood, Mangosteen and Lac

摘要

The objective of this research is to study the preparation of dye sensitized solar cell from red sandal wood, mangosteen and lac, respectively. The samples is extracted by acetone and purified with dichloromethen. The results show that the efficiencies of red sandal wood, mangosteen and lac are 1.47%, 0.78% and 0.27% respectively. Short circuit current densities are 7.83 mA/cm2, 2.65 mA/cm2 and 1.09 mA/cm2, respectively. Open circuit voltages are 0.39, 0.46 and 0.40, respectively.
