Abstract

Interfaces between organic electron-donating (D) and electron-accepting (A) materials can show efficient free charge carrier generation upon illumination, enabling organic photovoltaic devices and photodetectors with photon to electron conversion yields approaching 100%. Recently, organic light-emitting diodes (OLEDs) based on charge transfer (CT) (or exciplex) emission occurring at such D-A interfaces have been shown to exhibit high electroluminescence external quantum yields (EQEEL). However, no organic D-A combination with both a high EQEEL, as well as a high free carrier generation yield has been discovered so far. Such a system would result in significantly higher operating voltages in organic solar cells, reduced dark current in organic photodetectors, and reduced driving voltages for OLEDs.
