Scratching the Surface of Perovskites

Versatile compounds called perovskites are valued for their application in next generation solar energy technologies. Despite their efficiency and relative cheapness, perovskite devices have yet to be perfected; they often contain atomic-level structural defects.

New perovskite material shows promise alternative silicon

Silicon dominates solar energy products -- it is stable, cheap, and efficient at turning sunlight into electricity. Any new material taking on silicon must compete, and win, on those grounds. As a result of an international research collaboration have found a stable material that efficiently creates electricity - which could challenge silicon hegemony.

"Self-Healing" Polymer Brings Perovskite Solar Closer to Market

A protective layer of epoxy resin helps prevent the leakage of pollutants from perovskite solar cells, report scientists, adding a "self-healing" polymer to the top of a perovskite solar cell can radically reduce how much lead it discharges into the environment. This gives a strong boost to prospects for commercializing the technology.

The answer is blowing in the wind

The amount of energy generated by renewables fluctuates depending on the natural variability of resources at any given time. The sun isn't always shining, nor is the wind always blowing.

Lights, action, electrons!

Electrons are far too small and fast to be seen, even with the help of a light microscope. This has made measuring an electron's movement very difficult for the past century.

Nano-engineering electrodes to give tiny generators a boost

Could our waste be part of the answer to humanity's energy problems? Some researchers think so, thanks to bacteria that chow down on everything from sewage to heavy metals and give off electricity as one of their own waste products.
