Organic (opto) electronic materials have received considerable attention due to their
applications in thin-film-transistors, light-emitting diodes, solar cells, sensors, photorefractive …

Electronic properties of organic semiconductors are often critically dependent upon their
ability to order from the molecular level to the macro-scale, as is true for many other …

Conjugated polymer chains have many degrees of conformational freedom and interact
weakly with each other, resulting in complex microstructures in the solid state …

The optoelectronic properties of macromolecular semiconductors depend fundamentally on
their solid-state microstructure. For example, the molecular-weight distribution influences …

Efficient energy transport is desirable in organic semiconductor (OSC) devices. However,
photogenerated excitons in OSC films mostly occupy highly localized states, limiting exciton …

Most optimized donor‐acceptor (D‐A) polymer bulk heterojunction (BHJ) solar cells have
active layers too thin to absorb greater than∼ 80% of incident photons with energies above …

This article reviews some of our recent progress on materials design guidelines for
photoinduced charge generation in bulk-heterojunction organic solar cells. Over the last 7 …

Non-fullerene acceptors (NFAs) not only bring rapid efficiency progress to organic solar cells
(OSCs) but have also generated scientific interest in re-evaluating the photocharge …

Aggregate formation in poly (3‐hexylthiophene) depends on molecular weight, solvent, and
synthetic method. The interplay of these parameters thus largely controls device …

Recently, an intermixed phase has been identified within organic photovoltaic (OPV) bulk
heterojunction (BHJ) systems that can exist in addition to relatively phase-pure regions …
