Resumen
After reviewing literature and showing our own results, this paper summarizes some steps to extract, characterize and use natural dyes, proposing a protocol to obtain and work with these dyes. As an example of application, we use dye-sensitized solar cells (DSSCs). Dyes are the ?booster? of this sustainable energy source, and our exhaustive study contributes to the knowledge of dyes, and thus to improve cells? environmentally friendly design and performance.
