제목 Synthesis of All-Small-Molecules in Solar cells as Electron Acceptor
초록 Novel nonfullerene acceptors that include a variety of electron-deficient moieties have been blended with conjugated polymer electron donors to obtain photovoltaic performances that surpass those of fullerene acceptors. However, bulk heterojunction solar cells that employ nonfullerene smallmolecule acceptors and small-molecule donors have not been extensively studied. Semiconducting small molecules form well-defined intermolecular structures, have readily tunable energy levels, are easy to synthesize, and provide low batch-tobatch variations in the products, and high performances of solar cells incorporating semiconducting small molecules have been reported. In this study, we discovered that the small molecule acceptor shows promise for realizing all-small molecule solar cells and that the enhanced crystallinity of the blend film can improve the performances of this system.
