英文摘要 | A new J-series D-A copolymer J41 based on alkoxy-benzodithiophene (BDT)-alt-fluorobenzotriazole (FBTA) was synthesized with thieno[3,2-b]thiophene (TT) as pi-bridges. In comparison with its corresponding D-A copolymer J40 with thiophene pi-bridges, J41 shows a deeper HOMO energy level of -5.39 eV and slightly blue-shifted absorption. The polymer solar cells (PSCs) with J41 as donor and a low bandgap n-type organic semiconductor (n-OS) ITIC as acceptor exhibited a maximum power conversion efficiency (PCE) of 8.74% with a higher V-oc of 0.93 V, which is significantly improved in comparison with the PCE of 6.48% with V-oc of 0.89 V for the corresponding PSCs with J40 as donor. The results indicate that the pi-bridge engineering could further improve photovoltaic performance of the BDT-alt-FBTA-based D-A copolymers. |
