Machine learning helps researchers develop perovskite solar cells with near-record efficiency
Currently, one part of a solar cell is called the hole-transporting layer. Its purpose is to carry electron-hole pairs generated from a stable electron by a semiconductor after a photon is absorbed.

Molecular level changes translate to big efficiency gains for organic solar cells
giving electron-hole pairs. Excitons are bound tightly together, but sunlight with enough energy can cause them to dissociate ...
