Machine learning helps researchers develop perovskite solar cells with near-record efficiency
Its purpose is to carry electron-hole pairs generated from a stable electron by a semiconductor after a photon is absorbed. The effectiveness of such transport plays an important role in the ...

Positively spin coherent
However, two recent papers show that an even better bet could be the absence of one electron (known as hole) or more precisely its spin 1,2.
