Molecular packing structures in the active layers have a crucial impact on the electronic
processes for organic solar cells. To date, however, it is still difficult to probe molecular self …

Phenomena involving electron transfer are ubiquitous in nature, photosynthesis and
enzymes or protein activity being prominent examples. Their deep understanding thus …

We demonstrate that efficient and nearly field-independent charge separation of electron–
hole pairs in organic planar heterojunction solar cells can be described by an incoherent …

We discuss whether electron transfer from a photoexcited polymer donor to a fullerene
acceptor in an organic solar cell is tractable in terms of Marcus theory, and whether the …

The dissociation of excited electron–hole pairs is a microscopic process that is fundamental
to the performance of photovoltaic systems. For this process to be successful, the oppositely …

Herein, a generalized version of the entropy-ruled charge and energy transport mechanism
for organic solids and biomolecular aggregates is presented. The effects of thermal disorder …

In organic semiconductors, optical excitation does not necessarily produce free carriers.
Very often, electron and hole are bound together to form an exciton. Releasing free carriers …

The interface characteristic is a crucial factor determining the power conversion efficiency of
organic solar cells (OSCs). In this work, our aim is to conduct a comparative study on the …

Tracking the dynamics of ultrafast hole injection into copper thiocyanate (CuSCN) at the
interface can be experimentally challenging. These challenges include restrictions in …

This paper discusses the mechanism of generation of free charges in organic photovoltaic
cells (OPV) from electrostatically bound electron–hole pairs. The efficiency of this process is …
