dc.description.abstract | While it is widely recognized that microstructure plays an important role in the performance of organic
photovoltaics (OPV), systematic studies are often challenging, as varying the molecular packing through
typical chemical means (such as sidechain tuning) often affects the molecular energy levels, thus
preventing a clear correlation. In this work we present the synthesis of three perylene imide (PI) based
electron acceptors with almost identical energy levels, but distinct packing tendencies. We confirm our
initial hypothesis by measuring solution and solid-state absorption, and cyclic voltammetry as well as
characterizing the films by grazing incidence wide angle X-ray scattering (GIWAXS). In a second step, we
repeat the characterization of the three materials in blends with two polymer donors, namely PCDTBT
or PBDBT, whose energy levels are well aligned with those of the PI acceptors, and which, additionally,
exhibit different degrees of structural order. We show how the initial strong difference between
acceptors is partially blurred in blends, but still critical. Finally, we correlate our structural data with OPV
devices made with the corresponding six blends. Our data suggest that a good donor acceptor marriage
should ensure good energy alignment but also exhibit complementary crystallization tendencies of the
two components. | es |
