Organic photovoltaics are an important part of a next‐generation energy‐harvesting
technology that uses a practically infinite pollutant‐free energy source. They have the …

Recent progress regarding planar heterojunctions (PHJs) is reviewed, with respect to the
fundamental understanding of the photophysical processes at the donor/acceptor interfaces …

In bulk-heterojunction organic solar cells (BHJ-OSCs), exciton dissociation and charge
transport are highly sensitive to the molecular packing pattern and phase separation …

The molecular orientation and intermolecular interaction of photovoltaic polymers play a
crucial role in determining the blend film morphology, improving the exciton dissociation and …

There has been long-standing debate on how free charges are generated in donor: acceptor
blends that are used in organic solar cells, and which are generally comprised of a complex …

Disentangling the details of the vertical distribution of small semiconductor molecules
blended with polystyrene (PS) and the contact properties are issues of fundamental value for …

Multiple-angle incidence resolution spectrometry (MAIRS), originally developed in our
group, is a unique spectroscopic technique for analyzing the structure of molecular …

We present noncontact atomic force microscopy and Kelvin probe force microscopy studies
of nanophase segregated photovoltaic blends based on an oligothiophene–fluorenone …

This work introduces a novel family of CoII species having a curcuminoid (CCMoid) ligand,
9Accm, attached, namely [Co (9Accm) 2 (py) 2](1) and [Co (9Accm) 2 (2, 2′-bpy)](2) …

We present a comprehensive investigation of the charge-transfer (CT) effect in weakly
interacting organic semiconductor mixtures. The donor–acceptor pair diindenoperylene …
