Abstract

• PoneNaYeik petal (IxoraCoccinea) and TainPyarTaungNyo leaf (TradescantiaSpathacea) dyes were extracted with acidified solvent, ethanol to study the effects of solvent type on the extraction. UV-vis spectrometer can analyze the optical properties of these natural extract dyes. Characterization results showed high absorbance values 0.5494, 0.5845 and 0.3994 at 450 nm for PoneNaYeik dye. The sharp absorbance values in this study were 1.5244, 1.0997, 1.3577 at 435 nm and 0.9136, 0.6518, 0.7981 at 665 nm for TainPyarTaungNyo. The electrochemical properties of these dyes were observed by cyclic voltammetry (CV). These were indicative of the extract can be used as dye sensitized solar cells. Fourier Transmission Infrared Spectroscopy (FTIR) indicated the structural properties of these dyes.
