To enhance the performance of organic photovoltaics (OPVs), understanding the behavior of excitons and charges at organic layer interfaces is crucial. In this study, we evaluated the correlation between interfacial polarization charges and photovoltaic performance using acceptor molecules with similar molecular structures but exhibiting different potential gradients within the organic layer upon deposition. The results revealed that charge accumulation at organic interfaces, caused by negative polarization charges, deteriorates photovoltaic performance. Further discussions on the mechanism underlying this phenomenon will be presented during the session.
