英文摘要: Abstract(#br)Here we reported a nonfullerene electron acceptor based on perylene diimides, BP-PDI 4 , with a biphenyl core and four bulky PDI arms. BP-PDI 4 showed a twisted 3D structure which successfully suppressed the large aggregation of perylene diimides in active layer. BP-PDI 4 exhibited a wide optical band gap of 2.11 eV. Low-bandgap donor materials, namely PTB7-Th and PBDTTT-C-T, were chosen as donor materials for complementary absorption and well-matched energy levels. A PCE of 2.95% was achieved with V oc of 0.79 V, J sc of 10.61 mA cm −2 and FF of 35.2%, when PTB7-Th was used as donor material.
