Half a century after the synthesis of the first subporphyrinoid, the study of tripyrrole and
trisoindole porphyrin analogues constitutes a fervent and rapidly expanding research area …

Charge transfer (CT) between donors and acceptors following photoexcitation of organic
photovoltaics (OPVs) gives rise to bound electron–hole pairs across the donor–acceptor …

Understanding the factors affecting energy loss in organic photovoltaics (OPVs) is
imperative to achieve further improvements in their efficiency and to establish design rules …

The power conversion efficiency of organic photovoltaics is strongly limited by relatively
large energy loss, which is partially due to the disordered nature of organic semiconductors …

The notion of quasi‐equilibrium is central to most solar cells; however, it has been
questioned in organic photovoltaics (OPVs) owing to strong energetic disorder that frustrates …

Among the parameters determining the efficiency of an organic solar cell, the open-circuit
voltage (V OC) is the one with most room for improvement. Existing models for the …

This paper is a contribution to the Physical Review Applied collection titled Photovoltaic
Energy Conversion. We conduct comprehensive temperature-dependent measurements of …

In this work, we demonstrate several organic amorphous donor–acceptor systems that
exhibit sub-bandgap features over a more than 2 eV spectral range. An in-depth study of …

Intermolecular charge-transfer excitons play a central role in determining the performance of
organic solar cells as their voltage-dependent formation, dissociation, and recombination …

We employed bias-assisted charge extraction techniques to investigate the transient and
steady-state recombination of photogenerated charge carriers in complete devices of a …
