A series of two-dimensional conjugated polymers, namely PBDT2FBT-T1, PBDT2FBT-T2, PBDT2FBT-T3, and PBDT2FBT-T4, were designed and synthesized with four different chromophoric side chains. The oligothienyl units of the side chains highly enhanced the UV/vis-light absorption and charge carrier mobility, leading to an enlarged short current density (Jsc) of the polymer solar cell (PSC). PBDT2FBT-T3/PC71BM based PSC exhibited the power conversion efficiency of 6.48% in this series of polymers without any processing additives or post-treatments. |
