When an assembly of two or more molecules absorbs a photon to form a singlet exciton, and
the energetics and intermolecular interactions are favourable, the singlet exciton can rapidly …

Perylenediimide (PDI)-based acceptors offer a potential replacement for fullerenes in bulk-
heterojunction (BHJ) organic photovoltaic cells (OPVs). The most promising efforts have …

Four well-defined π-stacks of perylene bisimide (PBI) dyes were obtained in solution by
covalent linkage of two chromophores with spacer units of different length and sterical …

Singlet exciton fission (SF) in organic chromophore assemblies results in the conversion of
one singlet exciton (S1) into two triplet excitons (T1), provided that the overall process is …

Energy transfer in perylene-3, 4: 9, 10-bis (dicarboximide)(PDI) aggregates is often limited
by formation of a low-energy excimer state. Formation dynamics of excimer states are often …

Charge transfer states around the donor–acceptor interface in an organic solar cell
determine the device performance in terms of the open circuit voltage. In the present work …

The use of multiple chromophores as photosensitizers for catalysts involved in energy-
demanding redox reactions is often complicated by electronic interactions between the …

Time-resolved mid-infrared (TRIR) spectroscopy offers new opportunities to investigate how
the molecular and structural properties of optoelectronic materials influence their electronic …

Femtosecond time-resolved experiments demonstrate that the photoexcited state of
perylene tetracarboxylic acid bisimide (PBI) aggregates in solution decays nonradiatively on …

We present a simple and accurate GW implementation based on a combination of a Laplace
transform (LT) and other acceleration techniques used in post-self-consistent field quantum …
