Supramolecular n/p-Heterojunction Photosystems with Antiparallel Redox Gradients in Electron- and Hole-Transporting Pathways

摘要

The efficiency of organic optoelectronic devices depends on, among other things, their ability to generate charges and transport them to the electrodes. In bilayer and bulk n/p-heterojunction (BHJ) organic solar cells, electron (e~-)- and hole (h~+)-transporting materials are arranged in different ways for optimum charge transport, via highly ordered and conductive materials in the former and efficient charge separation at very large electron donor-acceptor interfaces in the latter.
