a Time-dependent contour maps of absorption spectra for the PYIT1:PBQx-TCl:rubrene system. b Time evolution of the PYIT1 absorption peak locations in PYIT1:PBQx-TCl and PYIT1:PBQx-TCl:rubrene systems. c, d AFM height images of the PYIT1:PBQx-TCl and PYIT1:PBQx-TCl:rubrene films. The scale bar is 400 nm. e, f TEM images of the PYIT1:PBQx-TCl and PYIT1:PBQx-TCl:rubrene films. The scale bar is 200 nm. g, h 2D GIWAXS patterns of the PYIT1:PBQx-TCl and PYIT1:PBQx-TCl:rubrene films. The colour scales represent the log of diffraction intensity, in the unit of counts. i The 1D GIWAXS integration curves along IP and OOP directions. PeakR represents the diffraction peak of rubrene. j Schematic illustration of the PYIT1:PBQx-TCl:rubrene film morphology.
