Abstract:The interfacial energetics are known to play a crucial role in organic electronic devices. However, their effects in organic thermoelectrics remain to be elucidated. In this work we optimize the output power density of an organic thermoelectric generator (OTEG) at ambient atmosphere to record high values, by varying the work function of the metal contacts. We find that the effect is linked to extended gradients of doping states, which are induced by humidity and reside inside the organic layer oriented perpen… Show more
