a J-V curves, b corresponding EQE spectra, c energy loss analysis and d photocurrent density versus Veff of the optimal OSCs based on PM6:asymmetric acceptors. The Jsccal represents integrated photocurrent density. The ηdiss and ηcoll represent the probability of exciton dissociation and charge collection, respectively. ∆E1 and ∆E2 are related to radiative recombination above and below the bandgap, respectively. ∆E3 is non-radiative recombination loss. e Electron and hole mobilities of PM6:asymmetric acceptors-based blend films calculated from space charge limited current (SCLC) mode. f Irradiation stability of the optimized OSCs based on PM6:asymmetric acceptors. Herein, the reported acceptor BTP-eC9 with a symmetric configuration is used as reference.
