Abstract

5-Methylene-6-oxo-5,6-dihydrothieno[3,2-b]thiophene-2-carboxylic acid was proposed as an electron-accepting unit in the design of organic donor-π-acceptor dye molecules. New organic dye incorporating a thieno[3,2-b]indole donor, a thiophene π-linker, and the abovementioned acceptor moiety was synthesized and evaluated as a photosensitizer for dye-sensitized solar cells. The photovoltaic device based on this dye achieved a power conversion efficiency of 0.95% with a short-circuit current density of 2.81 mA cm--2, an opencircuit voltage of 0.54 V, and a fill factor of 0.63 under standard AM 1.5 G solar irradiation (100 mW cm--2).
