DSSC fabrication using expensive and difficult to obtain synthetic dye sensitizers can be overcome by utilizing natural dyes from red cabbage. Dye or dye functions as a compound that absorbs sunlight. This study aims to explore the characteristics of anthocyanin pigments extracted from natural materials, namely red cabbage (Brassica Oleracea) as a dye-sensitizer in Dye Sensitized Solar Cell (DSSC) type solar cells. Anthocyanin pigments were chosen because of their ability to absorb light in a broad spectrum, their environmentally friendly nature, and their abundant availability in nature. Pigment extraction was carried out using 70% ethanol solvent and characterization was carried out using Fourier Transform Infrared Spectroscopy (FTIR) and UV-Visible (UV-Vis). The results of the FTIR analysis showed anthocyanin. UV-Vis analysis showed an absorption peak at a wavelength of 323 nm. The results of this study indicate that anthocyanin pigments from natural materials have the potential as effective and environmentally friendly dye-sensitizers in the development of DSSC
