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 …

The exciton, an excited electron–hole pair bound by Coulomb attraction, plays a key role in
photophysics of organic molecules and drives practically important phenomena such as …

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 …

The field of organic photovoltaics has developed rapidly over the last 2 decades, and small
solar cells with power conversion efficiencies of 13% have been demonstrated. Light …

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 …

The efficient transfer of energy between organic and inorganic semiconductors is a widely
sought after property, but has so far been limited to the transfer of spin-singlet excitons. Here …

The third generation of photovoltaic technology aims to reduce the fabrication cost and
improve the power conversion efficiency (PCE) of solar cells. Singlet fission (SF), an efficient …

The backscattering mean free path ξ, the average ballistic propagation length along a
waveguide, quantifies the resistance of slow light against unwanted imperfections in the …

Triplet excitons are ubiquitous in organic optoelectronics, but they are often an undesirable
energy sink because they are spin-forbidden from emitting light and their high binding …

Singlet exciton fission is an exciton multiplication process that occurs in certain organic
materials, converting the energy of single highly-energetic photons into pairs of triplet …
