Collection-limited theory interprets the extraordinary response of single semiconductor organic solar cells
Abstract
We demonstrate that, instead of the charge generation mechanism, charge collection can readily explain the bottleneck toward higher efficiency single organic semiconductor based OPVs (SS-OPVs). This change in archetype has the potential to transform the design rules for materials used in OPV devices and would inspire searches for a completely different set of polymers for OPV cells. Furthermore, we believe that our findings will broaden the understanding of the physics of charge transport and the impact of charged defect states in organic electronic devices. Hence, this work should have deep and immediate impact on the chemists, materials scientists, and device physicists in the field and would be of broad interest to the organic electronics community.
