It has been conducted a preparation of dye hybrid from purple sweet potato as a sensitizer in Dye Sensitized Solar Cell. In this research a variation of precursor pH in extracting antocyanin was carried out. Absorption spectra of purple-sweetpotatos dye was observed at wavelength range of 480-580 nm with strongest absorbance occured at 530 nm. The highest absorbance was resulted from the pH-1 s…
