The exciton diffusion length (LD) is a key parameter for the efficiency of organic optoelectronic devices. Its limitation to the nm length scale causes the need of complex bulk-heterojunction solar cells incorporating difficulties in long-term stabil

We present an investigation of the microscopic interplay between excitons and charge carriers by means of combined photoluminescence (PL) and charge carrier transport measurements on organic thin film transistors (OTFTs). For this purpose, the protot

In this work we address the microscopic effects related to the implementation of a Bathophenanthroline (BPhen) exciton blocking layer (EBL) sandwiched between Ag cathode and molecular Diindenoperylene (DIP)/C60 bilayer of a photovoltaic cell. Complem
