| 제목 | Design and Synthesis of Conjugated Random Terpolymer for High Performance Organic Solar Cells |
| 초록 | Polymer donors have been widely studied in Organic Solar Cells (OSCs) field for their advantages such as tunable the energy levels and light absorption range. To enhance certain properties of D-A copolymers, sometimes third monomers can be introduced to make D1-A1-D1-A2 or D1-A1-D2-A1 terpolymers. But studies about terpolymers have not been conducted much compared to D-A copolymers. In this study, we synthesized random terpolymers using three monomers: Cl-2DBDT as a donor unit; DT-fDTBT and BDD as acceptor units, each from D18-Cl and PBDB-T-Cl. We controlled the ratio of DT-fDTBT and BDD units to study the effect of acceptor units in optical, electrochemical, photovoltaic, orientational and morphological properties of the terpolymers. The absorption spectrum and energy levels of terpolymers lied between those of D18-Cl and PBDB-T-Cl depending on the ratio of each acceptor unit. However, optimized OSC devices showed higher PCE than devices fabricated with their mother copolymer donors. |
