a J-V curves and b corresponding EQE spectra of the optimal OSCs based on P3HT:E-2IFC-F and P3HT:Z-2IFC-F. The Jsccal represents integrated photocurrent density. c Statistical data of PCE and FF of P3HT-based OSCs in the literature and this work. d Photocurrent density versus Veff of the optimal OSCs. The ηdiss and ηcoll represent the probability of exciton dissociation and charge collection, respectively. e Electron and hole mobilities of P3HT:E-2IFC-F and P3HT:Z-2IFC-F blend films calculated from space charge limited current (SCLC) mode. f Irradiation stability of the optimal OSC devices based on P3HT:E-2IFC-F and P3HT:Z-2IFC-F.
