Regulating blend miscibility by adding multifluorinated polymer acceptors enables the development of 18% efficiency all-polymer solar cells
Three multifluorinated polymer acceptors were designed as the third component for ternary PM6:PY-IT blends. The PM6:PY-IT:PY4F-C20 device exhibited favorable phase separation (∼20 nm) and crystallinity, achieving a device efficiency of 18.0%.
