	abstract = {Two polymers, r-PDI-diTh and i-PDI-diTh, were synthesized as acceptors applicable for solution-processed BHJ OSCs. By introducing a bulky, dove tailed side chain and thereby suppressing the p-p interactions between perylenediimide units in the backbones of acceptor polymers, more effective phase segregation of these acceptors with a donor polymer (P3HT) was realized. By employing the inverted device configuration to better match the vertical phase separation of donor-acceptor polymers produced by solution processing, undesirable polaron pair recombination was suppressed, and PCE up to 2.17\% was achieved from the regio-regular acceptor r-PDI-diTh.},
