We synthesized medium-band-gap donor-acceptor (D-A) -type conjugated polymers (PBTZCZ-L and PBTZCZ-H) consisting of a benzotriazole building block as an acceptor and a carbazole unit as a donor. In comparison with the polymers, a small conjugated molecule (BTZCZ-2) was developed, and its structural, thermal, optical, and photovoltaic properties were investigated. The power conversion efficiency (PCE) of the BTZCZ-2-based solar cell devices was less than 0.5%, considerably lower than those of polymer-based devices with conventional device structures. However, inverted solar cell devices configured with glass/ITO/ZnO:PEIE/BTZCZ-2:PC71BM/MoO3/Ag showed a tremendously improved efficiency (PCE: 5.05%, Jsc: 9.95 mA/cm2, Voc: 0.89 V, and FF: 57.0%). We believe that this is attributed to high energy transfer and excellent film morphologies.

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.
