Abstract

Abstract: The search of sensitizers of natural dye for a solar cell has been intensively studied. One of the potentials as dye source is Pterocarpus Indicus Willd, PIW (L.) plant. The use of PIW extract dye for dye-sensitized solar cell (DSSC) application has rarely found in the literature. Such natural chlorophyll or flavonoid membrane could be used as mesoporous tissue in DSSC. It makes chlorophyll pigment attractive to be used as a sensitizer in solar cells. The natural dyes have been used with the combination of the metal oxide semiconductor to improve the DSSC performance. We used TiO2 as a working electrode due to its high thermal stability, non-toxic, low fabrication cost, and excellent optical properties. The primary objective is to obtain the structure, absorbance, and efficiency using dye concentration of immersion under of 12, 15, and 18 hours. We used chlorophyll extract of PIW leaves to soak the film composite TiO2 /ITO with a variation of dye immersion time. Method for deposition of film TiO2 was a slip casting and followed by heating at 500 o C for 1 hour. The counter electrode was the same structure with firstly been coated with carbon material on the conducting plane and drips using electrolyte. Both symmetric structures then taped together using a transparent flexible keyboard protector. The SEM analyses show that the more extended soaking of TiO2 surface dye becomes entirely dissolved by the dye solution. The UV-Vis characterization revealed that a 15 hours dye immersion time is resulting in the optimum absorbance. The highest result of I-V characterization is 12 hours immersion with a light intensity of 150 mW/cm 2 . The DSSC parameters obtained are Jsc of 0.370817 mA/cm 2, Voc of 0.400197 V and Efficiency equal to 0.035%. These results tell us that PIW chlorophyll extract has a potential for DSSC application.
