The 14th International Symposium on Functional π-Electron Systems, or Fpi14 for short, was held in Berlin from 2 to 7 June 2019. The conferences of the Fpi series cover the latest fundamental and applied progress in organic, polymer and hybrid materials. One of the focus areas at Fpi14 in Berlin was organic photovoltaics, which have made an unpredicted leap in efficiency due to the emergence of non-fullerene acceptor materials. Many of the topics covered by the Fpi14 fell directly into the scope of ReMorphOPV, for instance contributions on modelling transport processes in organic semiconductors and in-depth morphology characterizations of donor-acceptor blend materials.

Sebastian attended the Fpi14 and presented a work entitled “Watching Space Charge Build Up: Effect of Imbalanced Mobilities in Organic Solar Cells”. The conference was a great opportunity to broaden his knowledge of organic semiconductors and to get in touch with leading experts in the field.
