An international team of scientists has used machine learning to help them develop perovskite solar cells with near-record ...

One of the key components in these cells is the hole-transporting layer, responsible for moving the electron-hole pairs ...

A hole-transporting layer for perovskite solar cells with near-record efficiency has been developed using a machine learning algorithm. The work explored a vast region of chemical space much faster ...

Examples of such a dipole include an electron–hole pair in a semiconductor, which forms an exciton polariton, and the oscillating electrons at the surface of a metal, which creates a surface ...

It is the first time a stellar pair has been found in the vicinity of a supermassive black ... Astrophysicists Capture Astonishing Images of Gamma-Ray Flare from Supermassive Black Hole M87 Dec.

With SpaceX’s successful launch of the Starlink Group 12-6 mission on Tuesday, the curtain came down on a year that has seen ...

This interaction generates electron-hole pairs. Electrons move towards the Electron Transporting Layer (ETL) and holes towards the Hole Transporting Layer (HTL), creating an electric current.

The two black holes at the center of the two merging galaxies may, when close enough, form a pair bound by gravity. This pair may live for up to hundreds of millions of years before the two black ...
