Schematics of interfacial hole transfer in OPVs. a Two possible channels of hole transfer at a polymer heterojunction: (1) EX-mediated hole transfer and (2) iPP-mediated hole transfer. b Chemical structures of the polymer acceptor (N2200) and donor (J51) studied in this work. c Absorption spectra of J51 and N2200 (lower panel) are compared with the ICPE spectrum of an optimized device containing a J51/N2200 blend (upper panel)
