    Organic electronics have emerged as a viable competitor to amorphous silicon for the active layer in low‐cost electronics. The critical performance of organic electronic materials is closely related to their morphology and molecular packing. Unlike their inorganic counterparts, polymers combine complex repeat unit structure and crystalline disorder. This combination prevents any single technique from being able to uniquely solve the packing arrangement of the molecules. Here, a general methodology for combining multiple, complementary techniques that provide accurate unit cell dimensions and molecular orientation is described. The combination of measurements results in a nearly complete picture of the organic film morphology. The performance of organic electronic materials is closely related to their morphology and molecular packing, which can be measured by combining multiple complementary techniques. This image shows the layered structure of the semiconducting polymer pBTTT, determined by combining information from diffraction, polarized spectroscopies, and scanning probe microscopy.
