 Metal-organic sensitizing dyes


Since the Nature paper by O'Regan and Grätzel in 1991, Ru-based dyes have been the backbone of the dye-sensitized solar cell (DSSC) technology. Dyenamo offers four different Ru-based DSSC dyes known under the codes K77 (DN-FR01), B11 (DN-FR02), N749 (DN-FR03, Black dye) and C101 (DN-FR04).
