'Ideal' energy storage material for electric vehicles developed

The energy-storage goal of a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use has been achieved by a team of Penn State ...

Nanoscale 'Coaxial Cables' for Solar Energy Harvesting

Scientists have designed a new type of nanowire – a tiny coaxial cable – that could vastly improve a few key renewable energy technologies, particularly solar cells, and could even impact other cutting-edge, developing ...

Replacing lithium with sodium in batteries

An international team of scientists from NUST MISIS, Russian Academy of Science and the Helmholtz-Zentrum Dresden-Rossendorf has found that instead of lithium (Li), sodium (Na) "stacked" in a special way can be used for battery ...

Quantum Dots May Lead to Rainbow Solar Cell

For the first time, researchers have created solar cells made of different-sized quantum dots, each tuned to a specific wavelength of light. By arranging these quantum dots in an ordered pattern, the scientists hope that ...

First all-carbon solar cell

(Phys.org)—Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today.
