Organic dipolar compounds containing a 1,3-indandione-5,6-dicarboxylic acid moiety as an electron acceptor group were examined for the feasibility of using as the light harvesting material in dye-sensitized solar cells. Two compounds with triphenylamine donor moieties were synthesized by attaching it to 1,3-indandione-5,6-dicarboxylic acid. The device made with these simple dyes achieved a quantum yield up to 2.5%, which is comparable to the widely used dye made with cyanoacrylic acid. The spectroscopic properties of these compounds were analysed with the aid of theoretical models according to the time-dependent density functional theory.
