The power conversion efficiencies (PCEs) of single‐junction organic solar cells (OSC) have
now reached over 18%. This rapid recent progress can be attributed to the development of …

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

Bulk-heterojunction organic photovoltaic devices with nonfullerene acceptors (NFAs) exhibit
efficient hole transfer with small interfacial energy offset, which results in power conversion …

Reducing energy and voltage loss is an imperative area of improvement for the design of
organic solar cells (OSCs). Both in the context of charge generation and charge …

Over the last 5 years, research on the synthesis, device engineering, and device physics of
solution‐processed small molecule solar cells (SMSCs) has rapidly expanded …

Electrons are the workhorses of solar energy conversion. Conversion of the energy of light to
electricity in photovoltaics, or to energy-rich molecules (solar fuel) through photocatalytic …

A long standing question in organic electronics concerns the effects of molecular orientation
at donor/acceptor heterojunctions. Given a well-controlled donor/acceptor bilayer system …

Although organic heterojunctions can separate charges with near-unity efficiency and on a
subpicosecond time scale, the full details of the charge-separation process remain unclear …

In solar energy harvesting devices based on molecular semiconductors, such as organic
photovoltaics (OPVs) and artificial photosynthetic systems, Frenkel excitons must be …

The absorption of a photon usually creates a singlet exciton (S1) in molecular systems, but
in some cases S1 may split into two triplets (2× T1) in a process called singlet fission. Singlet …
