제목 | A push–pull organic semiconductor with efficient intramolecular charge transfer for solution processed small molecule OPVs |
초록 | Solution-processed small molecule solar cells (SMSCs) have the advantages over PSCs of high purity as well as well-defined structure and molecular weight without batch-to-batch variation, and so have received more and more attention. In order to improve SMSC performance and take full advantage of the properties of small molecules, further systematic research is required. In particular, improvements in active materials, especially in the donor materials, are vital to the production of high PCE SMSCs. In this study, a new push–pull organic semiconductor, Material designed and synthesized by lithiation, Suzuki coupling reaction. The structure of obtained material was confirmed by NMR, FT-IR and mass spectrometry (MS), and the physical properties were characterized by UV–vis spectroscopy, CV, DSC, and TGA. This material exhibits superior intramolecular charge transfer from the functionalized EW group, which produces an ED group that facilitates electron transfer into the active layer constituent PC71BM in a solar cell. |
