Thermal Expansion Behavior of PM6 Studied Using In Situ Wide-Angle X-Ray Scattering

In organic photovoltaics, even small morphological changes on the sub-nanometer scale can significantly impact the device’s performance. Such structural changes intrinsically occur due to the thermal response of a material, making a fundamental understanding of these processes essential. In this study, the thermal expansion of the high-performance donor material PDBD-T-2F (PM6) is characterized using in […]
