Solar energy is an ample renewable energy resource, with photovoltaic (PV) technology
enabling a direct route from light to electricity. Currently, PVs are limited in photon …

Using light to control matter has captured the imagination of scientists for generations, as
there is an abundance of photons at our disposal. Yet delivering photons beyond the surface …

Optically active molecular materials, such as organic conjugated polymers and biological
systems, are characterized by strong coupling between electronic and vibrational degrees of …

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

Singlet fission is a photophysical reaction in which a singlet excited electronic state splits
into two spin-triplet states. Singlet fission was discovered more than 50 years ago, but the …

Singlet exciton fission is a carrier multiplication process in organic semiconductors that
generates two electron–hole pairs for each photon absorbed. Singlet fission occurs on sub …

Open-shell molecules such as radicals, carbenes, and electronically excited-state molecules
exhibit high energies, and thus, in general, they are quite reactive. 1 The short-lived species …

Singlet fission (SF) has the potential to significantly enhance the photocurrent in single-
junction solar cells and thus raise the power conversion efficiency from the Shockley …

The ability to upconvert two low energy photons into one high energy photon has potential
applications in solar energy, biological imaging, and data storage. In this Letter, CdSe and …

Aromaticity is an important concept to understand the stability and physical properties of π-
conjugated molecules. Recent studies on pro-aromatic and anti-aromatic molecules …
