Light management significantly influences the photocurrent generation in all-perovskite tandem cells. Before photons reach the perovskite absorber layers, optical losses occur due to interfacial ...

Large-scale integrated sources of quantum light are enabling ingredients for the future of photonic quantum technologies. For such platforms, sources based on electrical injection are of value for ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

Metal halide perovskite light-emitting diodes (PeLEDs) have surpassed the 20% external quantum efficiency (EQE) limit for planar organic LED (OLED)-like device structures 1,2,3,4,5,6,7,8,9,10. The ...

Imagine the possibility of sending messages that are completely impervious to even the most powerful computers. This is the incredible promise of quantum communication, which harnesses the unique ...

Researchers are learning to flip light on and off one particle at a time, turning single photons into a controllable resource instead of a random byproduct of exotic materials. By engineering ...

Photonic quantum processors, devices that can process information leveraging quantum mechanical effects and particles of light (photons), have shown promise for numerous applications, ranging from ...

A new study shows that a solar sail may face drag force from the very light that powers it.
