Description

Of great importance for the field of organic electronics, and for many applied polymer and small molecule systems in general, is the study of vitrification-, solvent processing-, and substrate-induced structure formation (morphology). For example in an organic photovoltaic cell, the active layer will be a thin layer with a thickness on the order of 100 nm, sandwiched between organic or inorganic interlayers. Furthermore, these layers will be applied using specific solvent processing techniques such as spin coating or roll-to-roll coating. An additional complexity can be found in the thermal transitions of the active layer’s constituents. As a result, the active layer might develop a completely different structure than would be expected for the same materials in bulk. Thermal analysis techniques, a FYSC specialty, are uniquely suited to study such effects, as they not only give information on the ordered (crystalline) phase, but also on the amorphous (glass) phase. More specifically, the fast scanning chip
calorimetry technique, initiated during my PhD, can be used as this allows the analysis of thin layers at high scanning rates. The use of high scanning rates is an additional advantage as this makes it possible to obtain information on metastable states, which might be present in the early stages of structure formation and would transform before analysis is possible in conventional techniques. FYSC can therefore make a valuable contribution to this field in the coming years, both in terms of fundamental (understanding structure formation) and applied research (development of efficiency enhancing procedures).
