X-rays Reveal Why Adding a Bit of Salt Improves Perovskite Solar Cells

A team of researchers has reported new findings about perovskites that could pave the way to developing low-cost, high-efficiency solar cells. Using high-intensity X-ray mapping, they explain why adding small amounts of cesium and rubidium salt improves the performance of a promising class of solar cell materials, called lead-halide perovskites.

New Phenomenon Discovered that Fixes a Common Problem in Lasers: Wavelength Splitting

A team led by University of Utah physicists has discovered how to fix a major problem that occurs in lasers made from a new type of material called quantum dots. The never-before-seen phenomenon will be important for an emerging field of photonics research, including one day making micro-chips that code information using light instead of electrons.
