Carb your enthousiasm: Carbazole-based sensitizers with high extinction coefficients are synthesized for application in dye-sensitized solar cells (DSCs). The dyes perform efficiently with both iodine and cobalt electrolytes, showing power conversion efficiencies of up to 5.8 % on TiO2 films of 15 μm thickness, and retaining 90 % of their efficiency in devices with thinner films.
