Free charge photogeneration in a single component high photovoltaic efficiency organic semiconductor

Nature Communications, 2021
Organic photovoltaics (OPVs) promise cheap and flexible solar energy. Whereas light generates free charges in silicon photovoltaics, excitons are normally formed in organic semiconductors due to their low dielectric constants, and require molecular ...

Efficient energy transport in an organic semiconductor mediated by transient exciton delocalization [PDF]

Science Advances, 2020
Precisely tuning an organic semiconductor’s crystalline order allows exciton transport to proceed 2-3 orders of magnitude faster. Efficient energy transport is desirable in organic semiconductor (OSC) devices.

A substrateless, flexible, and water-resistant organic light-emitting diode

Nature Communications, 2020
Though organic light-emitting diodes (OLEDs) with impressive flexibility have been reported, achieving stable operation in air and moist environments remains difficult. Here, the authors report ultrathin OLEDs with hybrid thin-film encapsulation barriers

Red algae acclimate to low light by modifying phycobilisome composition to maintain efficient light harvesting

BMC Biology, 2022
Background Despite a global prevalence of photosynthetic organisms in the ocean’s mesophotic zone (30–200+ m depth), the mechanisms that enable photosynthesis to proceed in this low light environment are poorly defined.

Flexible and ultra-lightweight polymer membrane lasers

Nature Communications, 2018
Organic semiconductors provide a platform for flexible lasers, but these are still produced on rigid, thick substrates. Here, Karl et al. develop a method to make freestanding membrane lasers that can be transferred onto any substrate and show that these
