We present a systematic experimental and theoretical study of physical mechanisms governing the operation of polymer light‐emitting diodes. We show that through self‐consistent modeling we can address both charge transport and exciton generation. Electron and hole mobility in several polymers has been characterized experimentally. Characterization of excitons and especially of triplet‐excitons is achieved through use of a triplet‐emitting molecule.
