In this paper, the researchers analyze the effect of the PFN-Br interface layer on the performance and degradation of an OPV. The degradation (electric load) was showing a reduced FF and Jsc which they attributed to the contact modification, as it was absent for the devices without PFN-Br. The researchers used the characterization tool Paios. They performed multiple measurements to support the charge collection/extraction problem due to PFN-Br interface during degradation.
