Abstract
Dye-sensitized solar cells have been massive attention research because they are easy in fabrication, low-cost, sustainable, abundant material dye sources and high efficiency in power energy conversion. The natural dye that was extracted from Mimosa pudica Linn is potential to be used as a sensitizer for Dye-Sensitized Solar Cell. In this work, the dyes were extracted from three parts of plants; leaves, flowers, and the mix. TiO2 was used as the active material for semiconductor and applied by using the Doctor Blade method. Testing cells and the measurement of the voltage and the current were done outside under the sun irradiation. The UV - Vis spectra of the dyes indicated that the absorption of the three samples shows significant absorptions in quite similar wavelengths, approximately 665 nm. The DSSC cells had 0.16 %; 0.12 %; 0.01 % of conversion energy efficiency for flowers, leafs and mix respectively. These results indicated that the dye which is extracted from the flower of Mimosa pudica Linn is higher among all extracts.
