Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged "hole," moving together in a semiconductor. Created when an electron ...

Excitons, quasiparticles formed by an electron and a hole, transfer energy without a net charge. Physicist Ivan Biaggio ...

Scientists have unlocked the secret world of dark excitons — tiny energy carriers crucial for the future of solar power and ...

Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

How can the latest technology, such as solar cells, be improved? An international research team led by the University of ...

How can the latest technology, such as solar cells, be improved? An international research team is helping to find answers to questions like this with a new technique. For the first time, the ...

Under illumination, this built-in field propels photogenerated electron–hole pairs in opposite directions. Overcoming the absorption–extraction compromise. The best-performing solution ...

The results were published in Nature Photonics. Dark excitons are tiny pairs made up of one electron together with the hole it leaves behind when it is excited. They carry energy but cannot emit ...

The mechanism behind this performance relies on several complementary effects. Water molecules not only help separate the initial electron-hole pairs but also form organized channels that help ...

Dark excitons are tiny pairs consisting of an electron and the hole left behind when it becomes excited. They carry energy but do not emit light, giving them the name “dark.” An exciton can be ...

Boron fits into the crystal lattice just like silicon atoms, but since boron has only three electrons to use, a kind of hole is created where an electron ... applied to one pair of terminals ...
