Fabrication and Performance Test of Dye-Sensitized Solar Cell (DSSC) with Mango (Mangifera Indica) Leaf Extract as Sensitizer

Author(s): Arief Rahmatulloh, Mutia Devi Hidayati


In this research, we reported the fabrication of a dye-sensitized solar cell (DSSC) with mango leaf extract as a sensitizer. TiO2, which existed as a working electrode along with the sensitizer, has a role as a photocatalyst. TiO2 preparation with Indium Tin Oxide (ITO) glass was carried out by the doctor blade method, followed by the submersion of the TiO2–ITO glass at mango leaf extract. Carbon was added to act as the counter electrode. FTIR characterization is conducted to determine the interaction between dye sensitizer, TiO2, and ITO glass. The appearance of a new absorption at wave number 1498.73 cm-1 shows the interaction between dye sensitizer and TiO2–ITO glass. In addition, the emergence of absorption at wave numbers 580.59 and 420.57 cm-1 which stand for Ti–O and In–O respectively, strengthen the interaction existance between the dye and TiO2–ITO glass. The performance of DSSC was tested using a multimeter digital. The highest photovoltaic efficiency values of DSSC are obtained from a 2.5% sensitizer of 0.2188% under the sunlight.
