Control of Planarity of NDI-based n-Type Conjugated Polymers and Its Effects on Photovoltaic Performance of All-polymer Solar Cell |
| 초록 |
Systematic control of the chemical structure of conjugated polymers is critically important to elucidate the relationships between the conjugated polymer structures and properties and to optimize their performance in bulk heterojunction (BHJ) polymer solar cell (PSC) devices. In specific, control of planarity of conjugated polymers cause significant change in electrical properties. Naphthalenediimide (NDI)-based n-type conjugated polymers have low planarity because of asymmetric junction point for polymerization, and thus suffer from low electron mobility and have limitation in achieving high power conversion efficiency (PCE) of all-polymer solar cell. Herein, we synthesized symmetric NDI-based moiety with more fused rings and investigated the change in the planarity of new NDI monomer-based polymers and its effects on electrical properties. |
