One of the main problems of the dye sensitized solar cells (DSSCs) is the low stability, principally because of the degradation of the dye itself. Due to the fact that the most synthesized dyes are toxic, expensive, and difficult to synthesize, growing activities for using natural dyes have been reported. In this talk we will present the natural dyes we used in DSSCs. The dyes were extracted from specific plants growing in the Algerian Sahara such as Artemisia, Rosemary and Haloxylon.
