New, promising materials with high efficiency are constantly being discovered for organic solar cells. Often, these materials are chosen to mainly maximize efficiency. However, stability also plays an important role when selecting promising materials. The stability of organic materials depends on many variables, such as photochemical stability, photostability and morphological stability. In this analysis, we will attempt to gain a better understanding of nanostructural changes and hence morphological stability. [1] Using GIWAXS and absorption measurements, we systematically investigate how the ageing process affects the structure. In particular, we investigate the behaviour of the morphological ageing mechanisms, such as the orientation and aggregation of the material, as a function of temperature and substrate properties. These experiments are carried out on organic polymers such as PM6.
