An anode-free zinc battery that could someday store renewable energy

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…

First glimpse of polarons forming in a promising next-gen energy material

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. Read Full Article Here…

A polarization-driven guide to making high-performance, versatile solar cells

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…

Discovery of chromophores that emit light in the ultraviolet region when excited with visible light

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…

Benefits of renewable energy vary from place to place

A new study finds the environmental benefits of renewable power generation vary significantly, depending on the nature of the conventional power generation that the renewable energy is offsetting. The researchers hope the work will help target future renewable energy investments in places where they can do the most good. Read Full Article Here For more…

Solar cells: Mapping the landscape of Caesium based inorganic halide perovskites

Scientists have printed and explored different compositions of caesium based halide perovskites. In a temperature range between room temperature and 300 Celsius, they observe structural phase transitions influencing the electronic properties. The study provides a quick and easy method to assess new compositions of perovskite materials in order to identify candidates for applications in thin…
