Grazing incidence wide-angle X-ray scattering (GIWAXS) of thin films. GIWAXS of D-PDPP4T-HD thin films cast from different chloroform:1,2,4- trichlorobenzene (CF:TCB) solutions. a In-plane profile. b Out-of-plane profile. c Lamellar spacing (dlam) and π-stacking distance (dπ). Note that the scale in panel c is different for dπ and dlam
