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 …

Lanthanide-doped upconversion nanoparticles (UCNPs) are capable of converting near-
infra-red excitation into visible and ultraviolet emission. Their unique optical properties have …

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

This account aims at providing an understanding of singlet fission, ie, the photophysical
process of a singlet state (S1) splitting into two triplet states (2× T1) in molecular …

Triplet states have been widely studied in phosphorescent molecules, lanthanide complexes
and triplet–triplet annihilation systems, in which they have a critical role in energy transfer …

Silicon dominates contemporary solar cell technologies. But when absorbing photons,
silicon (like other semiconductors) wastes energy in excess of its bandgap. Reducing these …

The generation, control and transfer of triplet excitons in molecular and hybrid systems is of
great interest owing to their long lifetime and diffusion length in both solid-state and solution …

Colloidal quantum dots (CQDs), nanometer-scale semiconductor crystals capped with
surfactant molecules and dispersed in solution, have provided a powerful platform for the …
