Power Voltage Characteristics of Fabricated DSSC Incorporating Multiple Organic Dyes as Photosensitizer

Abstract

Two sets of Organic dyes were developed using kassod and senna plant leaves. The first sets of dyes are the organic dye from the leaves of two plants while the second set is the dye produce after combining together the dyes from the kassod and senna plants leaves. The two sets of dyes were used to sensitize the grown films. The films were characterized and the current voltage values of the grown films were obtained. The solar simulation result of the grown film for Kassod dyed TiO2 film was recorded for single dyes and for the combination of the two dyes. The result also covers absorbance of the spectra lines, absorbance coefficient values of the dyed TiO2, as well as transmittance and energy band gap values of the developed films. The precursors of tin (IV) chloride (SnCl4) (60%) and hydrofluoric acid (40%) was deposited on the cleaned soda-lime glass using the chemical vapour deposition method and nitrogen gas was supplied as a carrier gas through the bubbler to form the FTO layer. Titanium dioxide paste (TiO2) was deposited using a screen printing method to form M-TiO2.
