Molecular engineering of organic dyes containing N-aryl carbazole moiety for solar cell

Organic dyes containing N-aryl carbazole moiety are designed and synthesized. Under standard global AM 1.5 solar condition, the JK-25 sensitized cell gave a short circuit photocurrent density (Jsc) of 11.50 mA cm-2, an open circuit voltage (Voc) of 0.68 V, a fill factor of 0.66, corresponding to an overall conversion efficiency η of 5.15%, and the maximum incident monochromatic photon-to-current conversion efficiency (IPCE) of 77% at 430 nm.

NOVEL ORGANIC DYE CONTAINING N-ARYLCARBAZOLE MOIETY AND PREPARATION THEREOF

The present invention relates to novel dye containing N- arylcarbazole moiety and preparation thereof. The dye compound of the present invention which comprises fluorene and carbazole as an electron donor, a thiophene unit as a middle linking part, and rhodanine-3-acetic acid or cyanoacrylic acid as an electron acceptor can be used for a dye- sensitized solar cell (DSSC). The dye of the present invention shows improved molar absorptivity, Jsc(short circuit photocurrent density) and photoelectric conversion efficiency, compared to dyes of the prior art, and thus it can greatly improve solar cell efficiency. And, it can dramatically decrease dye synthesis cost because the dye of the present invention can be purified without using expensive columns.
