Suppressing the photon energy loss (Eloss ), especially the non-radiative loss, is of importance to further improve the device performance of organic solar cells (OSCs). However, typical π-conjugated semiconductors possess a large singlet-triplet energy gap (ΔEST ), leading to a lower triplet state...
