"incorporated polymer guests into the PM6:BTP-eC9 blend film to form entangled chain networks, thus improved the ductility and morphologically stability of the blend film. Due to the effective dissipation of local load caused by the entangled structure, the crack-onset strain of the developed ternary blend membrane is 17.14% higher than that of the traditional binary blend membrane. In addition, a stabilized PCE of 16.52% was obtained for the polyethylene terephthalate-substrate-based flexible OSCs"
