摘要：

The effects of thermal and solvent vapor annealing on the photovoltaic performance of a new class of all-conjugated poly(3-butylthiophene)-b-poly(3-hexylthiophene) diblock copolymer/PC71BM bulk heterojunction (BHJ) solar cells were scrutinized and theoretically analyzed using the single diode model combined with experimental measurements. The meanings of physical parameters in the model were elucidated in the context of crystalline order and phase separation to gain fundamental insight into the mechanism of annealing effects on the device performance of a new class of all-conjugated diblock copolymer-based BHJ solar cells.
