    This paper discovers the use of natural dyes from Roselle flower and Blue Pea flower which act as a sensitizer in DSSC and in addition has a potential in absorbing visible light spectrum. The dyes were extracted using distilled water (DI) and ethanol (E) extract solvent in an ultrasonic cleaner for 30 minutes with a frequency of 37 Hz by using 'degas' mode at the temperature of 30°C. Absorption spectra of roselle dye and blue pea dye with different extract solvent were tested using Evolution 201 UV-Vis Spectrophotometer. It was found that Roselle dye absorbs at a range of 400 nm - 620 nm and Blue Pea absorbs at the range of wavelength 500 nm - 680 nm. Fourier-Transform Infrared (FTIR) was used to identify the functional active group in extract dye. The concept of Dye-Sensitized Solar Cell (DSSC) similar to photosynthesis process has attracted much attention since it demonstrates a great potential due to the use of low-cost materials and environmentally friendly sources of technology.

    This paper presents an investigation on active components in nature based dyes as well as the electrical characteristic of both dyes from hibiscus and bougainvillea. Experiment was conducted using the Fourier transform infrared (FT-IR) spectroscopy to investigate the working components in the dyes pigment as well as solar simulator to simulate 1 sun radiance for the purpose of electrical data collection. Fabrication of the DSSC was done using Dr. Blade's method and as well as by using the carbon counter electrode. FT-IR shows that H-DI and H-Etha has important component such as the carboxyl and hydroxyl group which can bind to TiO2 to produce electron generation. As for the B-DI, carbonyl component as well as hydroxyl components was observe as well. In terms of its electrical performance, hibiscus pigment extract from di-water solvent exhibits high photoelectrical characteristic compare to B-DI, though the margin is small. Overall experiment shows that both dyes have potential in being used as dye as an alternative to their synthetic partner.
