  Design, synthesis and photophysical properties of A-D-A-D-A small molecules for photovoltaic application

  摘要：

  A series of linear-conjugated small molecule compounds featured with the acceptor-donor-acceptor-donor-acceptor (A-D-A-D-A) structure were designed, synthesized and characterized. The films of the compounds showed a broad UV-Vis absorption range of 300-800 nm with high molar absorption coefficient of more than 1.0 x 10(4) cm(-1). Their hole-mobility can be as high as 1.0 x 10(-3) cm(2) V-1 s(-1). The compounds have a compatible HOMO energy level of -5.0 eV to PC71BM and a high solubility up to 20 mg mL(-1) in chloroform. Therefore, compounds can blend with PC71BM in the chloroform and form an active layer for a photovoltaic cell device by spin-coating of the blend solution. A maximum power conversion efficiency of 3.2% was achieved with the DERH3TT solar cell device. These results indicate that the A-D-A-D-A small molecules with electron-withdrawing dyes as terminals are promising candidates for the high efficiency solution processed organic photovoltaic cells.

  HOMO level of the PBDTTT-based polymer was successfully reduced by introducing an keton group in place of the ester group. The average PCE of the PBDTTT-based devices reached 6.3% with a champion PCE result of 6.58%. Due to its highly efficient photovoltaic performance and more feasible synthesis approach, PBDTTT-C has the potential to be successfully applied in the large-scale manufacturing of polymer solar cells.
