Organic photovoltaics — Aqueous-based fabrication

The nature of the D:A pair, and in particular its interfacial energy, plays a role in particle formation and in their post-deposition treatment. It is therefore important not only to carefully select the pairs constituting the active layer but also to be able to adjust the chemical structure of the materials to achieve optimal D:A combinations. Consequently, it is necessary to conduct more fundamental studies on the systematic evaluation of chemical...
