An anode-free zinc battery that could someday store renewable energy
20 Jan 2021 at 5:50am
Renewable energy sources, such as wind and solar power, could help decrease the world's reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers have made a prototype of an anode-free, zinc-based battery that uses low-cost, naturally abundant materials.

First glimpse of polarons forming in a promising next-gen energy material
4 Jan 2021 at 10:19am
Polarons affect a material's behavior, and may even be the reason that solar cells made with lead hybrid perovskites achieve extraordinarily high efficiencies in the lab. Now scientists have used an X-ray free-electron laser to directly see and measure the formation of these ephemeral atomic lattice distortions for the first time.
A polarization-driven guide to making high-performance, versatile solar cells
4 Jan 2021 at 8:04am
When solar cells are exposed to sunlight, certain bound 'charge pairs' are generated in its components, which need to be separated for photocurrent generation. Ferroelectric materials, due to their spontaneous electric polarization, are highly efficient at charge separation but do poorly in light-to-electricity conversion. Now, scientists have demonstrated using theoretical calculations that antiperovskite oxides, a class of ferroelectric materials, show large absorption of sunlight, making them suitable photoabsorbers for thin film solar cells.

Discovery of chromophores that emit light in the ultraviolet region when exci...
18 Dec 2020 at 8:24am
Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When excited by visible light, the fluorescent dyes emit light in the ultraviolet region. According to the study, such light upconversion systems could boost the light-dependent reactions for which efficiency is important, such as solar-powered water splitting.
