Fig. 3

a Simulated dihedral distributions when π–π confinements are confined to 3 and 5 Å, respectively. The distribution broadens indicate the chains twisting at different temperatures. b Surface topographic AFM images (size: 5 µm × 5 µm) of the undoped and PZ1-doped films under thermal stress. c The one-dimensional GIWAXS line curves of the corresponding blends with respect to the OOP and IP directions. d The hole and electron mobilities of the corresponding films as a function of heating time at 150 °C. e Charge carrier lifetime obtained from TPV measurements as a function of charge carrier density (n) obtained from CE measurements under open-circuit conditions. f Normalized transient photocurrent (TPC) data for the undoped and PZ1-doped devices based on the relevant blends under thermal stress. Source data are provided as a Source Data file.
