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.
