Abstract: The physical organisation, from the molecular to the macro-scale, of essentially all macromolecular materials can profoundly affect the properties and features of the resulting architectures. I will discuss how rules that explain the mechanical properties of the Katana and distinguishes good from lesser tasty chocolates, can be applied to organic semiconductors to manipulate their properties and, hence, and their consequent performance when used as active layers in organic photovoltaic cells. To illustrate this, a survey will be given on the principles of structure development from the liquid phase with focus on how to use phase diagrams to manipulate their phase transformations and solid-state order for the controlled design and manipulation of the final ‘morphology’ towards technological and practical applications.
