Good solar cells from bad effects

Researchers used numerical simulations to demonstrate that energy dissipation and decoherence, which were thought to reduce solar cell efficiency, are counterintuitively helpful for the development of more efficient photovoltaics, offering a new guide to finding efficient photovoltaic materials.

A graphene barrier to precisely control molecules for making nanoelectronics

Scientists have developed a sheet of graphene material with minuscule holes in it that they could then place on a gold substrate. The holes allow molecules to attach to the gold exactly where the scientists want them, creating patterns that control the physical shape and electronic properties of nanoscale devices.

A simple artificial material can influence the properties of visible light

Metamaterials can be used to manipulate light for a range of applications, but often require complicated three-dimensional structures with features as small as a few tens of nanometers. Now, researchers have constructed a simpler, two-dimensional metasurface for state-of-the-art high-transmission light manipulation.
