Scientists Grow Lead-Free Solar Material With a Built-In Switch
A new ferroelectric material—grown in the lab from cesium germanium tribromide (CGB)—opens the door to an easier approach to making solar cell devices. Unlike conventional solar materials, CGB crystals are inherently polarized, where one side of the crystal builds up positive charges and the other side builds up negative charges, no doping required.

Scientists Uncover Surprising New Clues to Exotic Superconductors’ Superpowers
Researchers studied a model material (CeCoIn5) that mimics a cuprate superconductor that can be switched on and off using high magnetic fields. In chemical compositions where the superconductivity is strongest, the number of free electrons jumps, signifying a transition point. The researchers attributed this transition to the behavior of electrons associated with the cerium atoms. Read more »
How X-Rays Can Make Better Batteries
In order to help our nation meet its goal of net-zero carbon emissions by 2050, scientists like William Chueh and David Shapiro are working together to come up with new strategies to design safer, long-distance batteries made from sustainable, Earth-abundant materials. They discuss their pioneering work in this Q&A. Read more »
A Photoelectrode Protection Scheme for Solar-Fuel Production
Microscopy, spectroscopy, and computational studies of a promising artificial-photosynthesis material led researchers to develop a model photoelectrochemical (PEC) cell with remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels—ethylene and hydrogen.
