Synthesis and characterization of a triphenylamine-dibenzosuberenone-based conjugated organic material and an investigation of its photovoltaic properties

3,7-Bis[4-(diphenylamino)phenyl]-5 H-dibenzo[ a,d][7]annulen-5-one, containing triphenylamine- and dibenzosuberenone-based donor-acceptor-donor (D-A-D) conjugated moieties, is synthesized in high yield by Suzuki coupling of 5 H-dibenzo[ a,d][7]annulen-5-one with [4-(diphenylamino)phenyl]boronic acid. The most important part of the present study is the creation of a dye-sensitized solar cell structure using the synthesized organic molecule for the first time and the power conversion efficiency of this structure. Three solar cell devices are prepared and are named as first device, second device, and third device. The power conversion efficiency (%) value for first device, second device, and third device is calculated as 2.54, 2.38, and 2.54, respectively. Moreover, the chemical structure of the synthesized compound is determined by nuclear magnetic resonance, infrared, ultraviolet visible, fluorescence spectroscopy, and high-resolution mass spectrometry.
