Figure 4: Morphology of acceptors and IDTBR:P3HT blends.
From: High-efficiency and air-stable P3HT-based polymer solar cells with a new non-fullerene acceptor
(a) 2D GIXRD of O-IDTBR; (b) 2D GIXRD of O-IDTBR:P3HT (1:1); (c) DSC first heating cycles of O-IDTBR, P3HT and 1:1 blend; (d) 2D GIXRD of EH-IDTBR thin film; (e); 2D GIXRD of EH-IDTBR:P3HT (1:1); and (f) DSC first heating cycles of EH-IDTBR, P3HT and 1:1 blend. Thin films for GIXRD were processed using the same conditions as described for optimized devices and DSC drop-cast samples were measured at 5 °C min−1. Thermograms are offset vertically for clarity.
