Reshaping the solar spectrum to turn light to electricity

When it comes to installing solar cells, labor cost and the cost of the land to house them constitute the bulk of the expense. The solar cells—made often of silicon or cadmium telluride—rarely cost more than 20 percent ...

Simulations lead to design of near-frictionless material

Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. Argonne ...

Physicists fine-tune control of agile exotic materials

Physicists have found a way to control the length and strength of waves of atomic motion called polaritons that have promising potential uses such as fine-scale imaging and the transmission of information within tight spaces. ...
