In situ X‐ray measurements give insight into the effect of substrate temperature on the structural evolution of doctor–bladed poly(3‐hexylthiophene):[6,6]‐phenyl‐C 61 butyric acid methyl ester (P3HT:PCBM) blends during the transition from wet to solid. Drying the active layer at lower temperature (10 °C) leads to a better nanomorphology with a finer interpenetrating network, and may be an easy route for the optimization of the performance in doctor–bladed solar cells.
