Abstract

Careful selection of processing solvents to tune optimal active layer morphology in a donor-acceptor copolymer blend [PTB7:P(NDI2OD-T2)] yields bulk heterojunction microstructures with intradomain percolative pathways and enhanced charge transport. Such microstructures afford all-polymer solar cells with power conversion efficiencies as high as 2.7%.
