    Abstract

    The properties of singlet and triplet excitons are compared in organic materials for applications in optoelectronic organic solar cells (OSCs) and organic light emitting devices (OLEDs). It is found that by managing the organic material designs both singlet and triplet excitons can be beneficially used in OSCs and OLEDs equally well. A model of dissociation of excitons excited in the acceptor material of the bulk heterojunction organic solar cells is presented. It is shown that the dissociation of acceptor excitons also can contribute to the photovoltaic performance of OSCs.
