中文摘要	two new donor-acceptor copolymers containing carbazole and thieno[3,2-b]quinoxaline units with meta- and para-positioned alkoxy groups on the peripheral phenyl rings, pcttqx-m and pcttqx-p, were designed and synthesized. their thermal stability, uv-vis absorptions, energy levels and photovoltaic properties were investigated. compared with their quinoxaline analogues using carbazole and quinoxaline derivatives as donor and acceptor units, by simply fusing a thiophene ring to the quinoxaline unit, pcttqx-m and pcttqx-p not only exhibit lower bandgaps (similar to 1.8 ev) but also maintain deep homo energy levels (similar to-5.3 ev). a polymer solar cell based on pcttqx-m with the structure ito/pedot:pss/polymer:pc71bm/lif/al showed a promising pce of 4.40% with a rather high open circuit voltage of 0.89 v, a short circuit current of 9.03 ma cm(-2) and a fill factor of 0.54, which was higher than that of pcttqx-p (3.45%). after solvent vapor annealing treatment, the pce of the polymer solar cell based on a pcttqx-m/pc71bm blend film could be further improved to 5.31%.
