| 英文摘要 | A thieno[3,4-b]thibphene-based donor polymer PTBTz-2 was employed to construct fullerene-free solar cell with the classical acceptor ITIC. Interestingly, due to the high extinction coefficients and wide absorption for these two materials, the active layer can harvest a larger fraction of the coverage solar spectrum even in ultrathin film. Furthermore, the simultaneous advantages of appropriate cascade energy level, well-balanced hole/electron mobility (mu(h)/mu(e) = 1.16), and low charge accumulation and recombination, make the PTBTz-2/ITIC-based solar cells exhibit an excellent power conversion efficiency of 10.92% with large short circuit current density of 20.34 mA cm(-2). The results indicate that fine-tailored thieno [3,4-b]thiophene-based polymers would be another type of promising donor materials, except for widely reported efficient benzo[d][1,2,3]triazole (BTA)- or benzo[1,2-c:4,5-c']-dithiophene-4,8-dione (BDD)-based polymers, and would enrich the reservoir of high-performance light-harvesting conjugated polymers. |
