Perovskite solar cells are cheaper to make than traditional silicon cells and their electricity conversion efficiency is improving rapidly. To be commercially viable, perovskite cells need to scale up from lab size. Researchers report a method for making perovskite cells larger while maintaining efficiency.

Electron orbitals provide information on the whereabouts of the electrons in atoms and molecules. Scientists have now succeeded in experimentally recording these structures in all three dimensions. They achieved this by further developing a method they had already applied two years ago to make these orbitals visible in two dimensions.

To understand how a TMD semiconductor behaves inside a device, researchers investigated the effects of sub-monolayer deposition of alkali atoms at the surface of the semiconductor tungsten selenide. These deposited atoms mimics the electric field effects that a semiconductor would experience inside a transistor, while allowing researchers to directly analyse the electronic structure by a state of the art spectroscopic technique.
