Recent years have witnessed an explosion of interest in quantum devices for the production,
storage, and transfer of energy. This Colloquium concentrates on the field of quantum …

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

The chemical structure of donors and acceptors limit the power conversion efficiencies
achievable with active layers of binary donor-acceptor mixtures. Here, using quaternary …

The intrinsic electronic properties of donor (D) and acceptor (A) materials in coupling with
morphological features dictate the output in organic solar cells (OSCs). New physical …

Van der Waals heterostructures have recently emerged as a new class of materials, where
quantum coupling between stacked atomically thin two-dimensional layers, including …

Non-fullerene acceptors have recently attracted tremendous interest because of their
potential as alternatives to fullerene derivatives in bulk heterojunction organic solar cells …

The status of understanding of the operation of bulk heterojunction (BHJ) solar cells is
reviewed. Because the carrier photoexcitation recombination lengths are typically 10 nm in …

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 …

Understanding the charge-separation mechanism in organic photovoltaic cells (OPVs) could
facilitate optimization of their overall efficiency. Here we report the time dependence of the …

Solution processed single junction polymer solar cells (PSCs) have been developed from
less than 1% power conversion efficiency (PCE) to beyond 9% PCE in the last decade. The …
