제목 | Quinacridone-based donor–acceptor conjugated polymers with a broad absorption in the visible range. |
초록 | Solar cells based on conjugated polymeric materials have recently received considerable attention due to their low-cost solution fabrication process, light weight, large area and flexible panels as well as potential contribution to clean and renewable energy. Low band gap conjugated polymers with main chain alternating D-A structure are promising, which can broaden the absorption to the red and even to the near IR region via the so-called internal charge transfer and result in higher PCE. In this study, we synthesized alternating polymers containing isoindigo derivatives through Suzuki coupling reaction. Thus, polymer was investigated physical, optical, electrochemical and photovoltaic properties. Photovoltaic properties of this polymer were investigated by fabricating bulk-heterojunction photovoltaic device using this polymer as electron donor and PCBM as the acceptor. |
