| 제목 | Medium Bandgap Donor Polymers incorporating a Novel Ester-Substituted Acceptor for Efficient Non-Fullerene Solar Cells |
| 초록 | Two novel Donor-Acceptor (D-A) copolymers P1 and P2 incorporating novel ester substituted acceptor and benzo[1,2-b:4,5-b′]dithiophene (BDT) units have been synthesized and characterized. The new polymers featured complementary absorption and favorable energy levels to match the non-fullerene acceptor ITIC. The incorporation of carboxylate unit on the acceptor leads to lower lying highest occupied molecular orbital (HOMO) energy levels and easy tuning of solubility in the resulted polymers. In the preliminary studies, photovoltaic devices of polymers P1 and P2 blended with ITIC acceptor demonstrated power conversion efficiency (PCE) of 6.4% and 5.5%, respectively. Further studies are currently underway to optimize the solar cell performance. |
