| 英文摘要 | Two novel small molecules (SMs) of BDT(TPD-DPP)(2) and BDTT(TPD-DPP)(2) with a D(A-A')(2) framework were designed and synthesized, in which the electron-rich benzodithiophene (BDT) and thiophenyl-substituted benzodithiophene (BDTT) are used as a central donor (D) core, as well as the electron deficient diketopyrrolopyrrole (DPP) and thieno [3,4-c]pyrrole-4,6-dione (TPD) as dual acceptor (A and A') units, respectively. Their optical, electrochemical, and photovoltaic properties were investigated together with their counterparts, which bearing an accepter-donor-accepter (A-D-A) architecture. Wider and stronger solar photon responses and decreasing the lowest unoccupied orbital (LUMO) levels are observed in the D(A-A')(2) rather than A-D-A type SMs. The significantly increasing power conversion efficiency of 4.25% with a short-circuit current density of 10.08 mA cm(-2) were obtained in the BDTT(TPD-DPP)(2) based solar cells. This work demonstrates that using D(A-A')2 architecture with dual acceptor units is an effective method to improve photovoltaic performance of SMs for solution-processed organic solar cells.
