Fig. 6: GIWAXS characterization of the neat films and blended films.
From: A rare case of brominated small molecule acceptors for high-efficiency organic solar cells
a 2D GIWAXS patterns of CH20, CH21 and CH22 neat films and b optimized PM6:CH20, PM6:CH21 and PM6:CH22 blended films. c The corresponding in-plane (IP) and out-of-plane (OOP) extracted line-cut profiles of CH20, CH21 and CH22-based neat and blended films.
