New organic dye based on a 3,6-disubstituted carbazole donor for efficient dye-sensitized solar cells

We have synthesized and characterized four organic dyes (H1-H4) based on a 3,6-disubstituted carbazole donor as sensitizers in dye-sensitized solar cells. These dyes have high molar extinction coefficients and energy levels suitable for electron transfer from an electrolyte to nanocrystalline TiO2 particles. Under standard air mass 1.5 global (AM 1.5 G) solar irradiation, a device using dye H4 exhibits a short-circuit current density (Jsc) of 13.7 mA cm-2, an open-circuit voltage (Voc) of 0.68 V, a fill factor (FF) of 0.70, and a calculated efficiency of 6.52 %. This performance is comparable to that of a reference cell based on N719 (7.30 %) under the same conditions. After 1000 hours of visible-light soaking at 60 °C, the overall efficiency remained at 95 % of the initial value. Metal-free sensitizer: Four organic dyes based on a 3,6-disubstituted carbazole donor have been synthesized for their potential use as sensitizers in dye-sensitized solar cells. These dyes have high molar extinction coefficients and energy levels suitable for electron transfer from an electrolyte to nanocrystalline TiO 2 particles. Under standard global AM 1.5 solar irradiation, a device using one of the prepared dyes (see graphic) exhibited a calculated efficiency of 6.52 %.
