a–d, Line cuts of in situ spin coating 2D GIWAXS profiles with the integrated azimuthal angle range from −10° to 10° (out-of-plane direction) for PM6:BTP-TO2 in CB (a), PM6:BTP-TO2 in PX (b), PM6:BTP-TC8 in CB (c), PM6:BTP-TC8 in PX (d), in going from solution to film. e,f, Line cuts of 2D GIWAXS profiles with the integrated azimuthal angle range from −10° to 10° (out-of-plane direction) for PM6:BTP-TO2 films fabricated by using CF, TL, PX and CB (e), PM6:BTP-TC8 films fabricated by using CF, TL, PX and CB (f). The scale of the y axis is linear. The scale of the Q vector is the scattering wave vector transfer.
