| 제목 | D-A Type Copolymer Based on Thieno[3,2-b]thiophene and Isoindigo for Polymer Solar Cells |
| 초록 | Polymer solar cells(PSCs) have become the focus of tremendous research due to their a lot of advantages such as low-cost, light-weight, solution process, flexibility, and so on. For a promising strategy for designing photovoltaic polymer, donor-acceptor (D-A) alternating copolymer is a good choice which can be fine-tuned by the combination of a variety of D and A building blocks and expected to achieve high performance. In this study, thieno[3,2-b]thiophene as an electron donor and isoindigo as an electron acceptor were synthesized by Stille coupling reaction. Isoindigo is one of the good acceptor units which has promising absorption property in the long wavelength region and leads to narrow band gap. The physical, optical and electrochemical properties of the synthesized polymer were characterized and the devices were fabricated and characterized photovoltaic properties. |
