中文摘要	two phenazine donor-acceptor-conjugated copolymers (p1 and p2) with the same polymer backbone but different anchoring positions of alkoxy chain on the phenazine unit were investigated to identify the effect of changing the position of alkoxy chains on their optical, electrochemical, blend film morphology, and photovoltaic properties. although the optical absorption and frontier orbital energy levels were insensitive to the position of alkoxy chains, the film morphologies and photovoltaic performances changed significantly. p1/pc71bm blend film showed the formation of phase separation with large coarse aggregates, whereas p2/pc71bm blend film was homogeneous and smooth. accordingly, power conversion efficiency (pce) of photovoltaic devices increased from 1.50% for p1 to 2.54% for p2. in addition, the pce of the polymer solar cell based on p2/pc71bm blend film could be further improved to 3.49% by using solvent vapor annealing treatment. these results clearly revealed that tuning the side-chain position could be an effective way to adjust the morphology of the active layer and the efficiency of the photovoltaic device.
