DYE-SENSITIZED SOLAR CELL USING EOSIN Y DYE IN VARIOUS CONCENTRATIONS

Abstract

This work investigated the effect of various concentrations of Eosin Y dye on the performance of the Dye-sensitized solar cell (DSSC). Distinct concentrations like 10 mg, 20 mg and 30 mg of Eosin Y Dye were prepared for the construction of DSSC. For preparation of photoanode, Titanium dioxide nanoparticles were used to prepare paste, which was deposited on fluorine doped tin oxide (FTO) glass substrate by Doctor blade technique. Absorption spectra of the dyes were taken, and the photovoltaic performance was measured for the fabricated cells. The highest efficiency is obtained by the cell with 10 mg of Eosin Y which is 0.39%. The conversion efficiency of the cells with 20 mg and 30 mg of Eosin Y are 0.007% and 0.0015% respectively.
