Molecular Donor‐Acceptor Dyads for Single‐Material Organic Solar Cells Open
A series of ambipolar covalently linked oligothiophene‐fullerene dyads have been synthesized by systematical structural variations. In this respect, the length of linker between donor and acceptor unit was altered and in a second series th…

Quantitative Analysis of Charge Dissociation by Selectively Characterizing Exciton Splitting Efficiencies in Single Component Materials Open
Exciton dissociation between donor and acceptor is the decisive process to determine the photovoltaic performance of organic solar cells (OSCs). The rather fast dynamics of photo‐induced charge generation in well‐optimized bulk heterojunct…
