The role of third component in coumarin-based all-small-molecule ternary organic solar cells with non-fullerene acceptor based on molecular stacking.

The power conversion efficiency (PCE) of ternary all-small-molecule organic solar cells (T-ASM-OSCs) differs significantly from that of the polymer systems (2 %), and the role of third component remains unclear. The electron donor of coumarin derivatives with simple structure and strong and broad light absorption has high PCE for T-ASM-OSCs composed of non-fullerene acceptors (Y6 and DBTBT-IC). Here, we calculated the electronic structure and interfacial properties of the binary C1-CN:Y6 and ternary C1-CN:Y6:DBTBT-IC systems using molecular dynamic (MD) simulations and density functional theory (DFT) to explore the role of the third component (DBTBT-IC).
