Metal-Halide Perovskite Semiconductors Can Compete with Silicon Counterparts for Solar Cells, LEDs

Common semiconductor materials for solar cells, such as silicon, must be grown via an expensive process to avoid defects within their crystal structure that affect functionality. But metal-halide perovskite semiconductors are emerging as a cheaper, alternative material class, with excellent and tunable functionality as well as easy processability.

Science snapshots from Berkeley Lab

New Berkeley Lab breakthroughs: engineering chemical-producing microbes; watching enzyme reactions in real time; capturing the first image of ‘electron ice’; revealing how skyrmions really move

Driving Water Splitting to Create Chemical Fuels

Scientists improved the performance of bismuth vanadate, an electrode material for converting solar energy to hydrogen—an energy-dense and clean-burning fuel.

Decorating Semiconductors at the Atomic Scale

Combining two different semiconductors can create new properties. The way these combinations work depends on how the semiconductors are arranged and contact one another. Researchers have developed a new way to grow semiconductor crystals about 100,000 times smaller than the width of a human hair. This new synthesis method independently controls the arrangements and sizes of the crystals.

Breaking the Power & Speed Limit of Lasers

SUMMARYResearchers at the George Washington University have developed a new design of vertical-cavity surface-emitting laser (VCSEL) that demonstrates record-fast temporal bandwidth. This was possible by combining multiple transverse coupled cavities, which enhances optical feedback of the laser. VCSELs have emerged…
