“…In addition, the quasi-degenerated excited states between CT and hybrid excitation, corresponding to two excited states with very tiny energy difference, can enhance photon harvesting and are favorable to improve J SC . [56,57] For instance, the quasi-degenerated S7 and S8 of C8-ITIC correspond to the largest J SC (19.7 mA cm −2 ) among these OSCs in this work. [15] The charge density difference (CDD), transfer amount (Δq) and CT distance (Δd) were adopted to quantify the excitation properties.…”

“…In this way, the excitons generated by light absorption are dissociated inside the molecules, and the generated carriers are also transported within the molecules, which fundamentally avoids the influence of phase separation between the donor and acceptor on the dissociation of excitons. [29][30][31][32][33][34][35] Porphyrin molecules are macrocyclic conjugated electron-rich compounds that can act as electron donors and exhibit strong absorption in the visible light region. 36,37 By contrast, fullerenes are electron-deficient molecules that can act as electron acceptors 38 and show strong absorption in UV region.…”
