Three new organic dyes comprising carbazole, iminodibenzyl and phenothiazine moieties, as electron donors and di-anchoring rhodanine rings as the electron acceptors, were synthesized and evaluated for use in dye-sensitized solar cells. A solar cell employing dye-containing phenothiazine as a hole-transporting unit and di-anchoring rhodanine rings as the electron acceptors exhibits a short circuit photocurrent density of 10.6 mA cm -2, an open-circuit voltage of 0.658 V and a fill factor of 0.7, corresponding to an overall conversion efficiency of 4.91percent at standard AM 1.5 sunlight. ?2011 Sociedade Brasileira de Qui?mica.

Hexyl carbazole derivatives are one of the most prominent dye scaffolds in the dye-sensitized solar cells (DSSCs). New substituted carbazole dyes such as DRA-HC, DCA-HC, and DTC-HC were synthesized for DSSCs. These dyes are containing hexyl moiety as electron donor and rhodanine-3-acetic acid, cyanoacetic acid and tetracyanoethylene as an electron acceptor linked to carbazole moiety. The relation between dye structures, photophysical/electrochemical, molecular structure and DSSC manufacturing had been discussed. All structures showed more positive ground-state oxidation potential than I?/I?3 and more negative excited state oxidation potential than the conduction band edge of the semiconductor. The highest efficiency of the DSSCs was obtained in the case of DCA-HC dye (η = 1.41%, VOC = 708?mV, FF = 0.81, and JSC = 2.45?mA?cm?2 with 100?mW?cm?2) compared to other synthesized dyes.
