| 英文摘要 | In this work, we fabricated high efficient ternary PSCs based on two compatible non-fullerene acceptors (IDIC and ITIC) with similar chemical structures and one new D-A-type polymer (PSTZ) donor. By inserting ITIC into the binary PSTZ: IDIC system, the active layer show smooth and gradient energy levels, improved crystallinity and optimized morphologies, which results in efficient exciton separation, charge transport and collection. As a result, the optimal ternary PSCs based on PSTZ: ITIC: IDIC (1:0.1:0.9) exhibited a higher PCE of 11.1% with a V-oc of 0.953 V, J(sc) of 17.4 mA cm(-2) and FF of 66.9% in comparison with those of binary PSC systems based on PSTZ: IDIC (PCE of 8.06%) or PSTZ: ITIC (PCE of 8.13%). These results indicate that combining two compatible nonfullerene acceptors with similar structures to fabricate ternary PSCs should be a promising strategy to enhance the photovoltaic performance of the PSCs. |
