Fabrication and characterization of dye-sensitized solar cell using Syzygium cumini dye

Abstract

Dye-Sensitized solar cell (DSSC) has long been regarded as one auspicious choice for the alternative way to convert the solar energy to electric energy. In this work, DSSC has been fabricated using the natural dye extracted from Syzygium cumini fruits. Here, nanocrystalline TiO2 deposited on the fluorine doped tin-oxide (FTO) glass substrate has been used as dye absorber due to their high surface area and it shows high electron mobility, and carbon counter electrode has been used as a back electrode. The performance parameters of the solar cell have been achieved under AM 1.5 illumination. Optical and surface morphological studies of TiO2 film have been observed. The solar cell efficiency of 0.161%, short circuit current density of 0.952 mA/cm2, open circuit voltage of 735 mV and fill factor of 0.230 have been achieved in this study.
