英文摘要	the correlated donor/acceptor (d/a) molecular orientation plays a crucial role in solution-processed all-polymer solar cells in term of photovoltaic performance. for the conjugated polymers ptb7th and p(ndi2od-t2), the preferential molecular orientation of neat ptb7-th films kept face-on regardless of the properties of processing solvents. however, an increasing content of face-on molecular orientation in the neat p(ndi2od-t2) films could be found by changing processing solvents from chloronaphthalene (cn) and o-dichlorobenzene (odcb) to chlorobenzene (cb). besides, the neat p(ndi2od-t2) films also exhibited a transformation of preferential molecular orientation from face-on to edge-on when extending film drying time by casting in the same solution. consequently, a distribution diagram of molecular orientation for p(ndi2od-t2) films was depicted and the same trend could be observed for the ptb7-th/p(ndi2od-t2) blend films. by manufacture of photovoltaic devices with blend films, the relationship between the correlated d/a molecular orientation and device performance was established. the short-circuit current (j(sc)) of devices processed by cn, odcb, and cb enhanced gradually from 1.24 to 8.86 ma/cm(2) with the correlated d/a molecular orientation changing from face-on/edge-on to face-on/face-on, which could be attributed to facile exciton dissociation at d/a interface with the same molecular orientation. therefore, the power conversion efficiency (pce) of devices processed by cn, odcb, and cb improved from 0.53% to 3.52% ultimately.
