Study of Dye Sensitized Solar Cell using Mirabilis Jalapa Flower Extract

Abstract

Dye sensitized solar cells (DSSC) are a promising class of photovoltaic cells with the capability of generating green energy at low cost. No expensive equipment are required in their fabrication. In our work, we have constructed the solar cell with dye extracted from Mirabilis Jalapa (Four o’clock flower) as natural sensitizers.TiO2 thin flim was coated on FTO conducting glass plate. The prepared dye was coated on it. A blend of KI, Ethylene glycol and iodine was used as an electrolyte. The prepared cells were characterised with FT-IR spectrometer and UV-Vis spectrophotometer. I-V characteristic curves were traced and its efficiencies were calculated. The efficiency of Dye sensitized solar cells (DSSC) was calculated.
