Excitonic spin engineering for solar cells and organic light-emitting diodes

The last two decades have seen renewed interest in molecular organic semiconductors. Since these materials support the formation of excitons, their behavior differs considerably from their inorganic counterparts. This gives rise to a variety of novel properties that can be exploited to create entirely new or improve existing optoelectronic devices. In this thesis, we explore excitonic concepts for improving both organic-light emitting diodes (OLEDs) and silicon solar cells. OLEDs are already commercially successful. However they still suffer from several major drawbacks. Multiexcited-state phenomena are believed to be the root cause of challenges like efficiency roll-off and degradation. The development of novel strategies to reduce exciton densities under heavy load is therefore highly desirable.
