Battery technology with off-the-charts charging capacity

Battery technology with off-the-charts charging capacity

Apr 27, 2016 United States
Researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement.
Flipping a chemical switch helps perovskite solar cells beat the heat

Flipping a chemical switch helps perovskite solar cells beat the heat

Apr 27, 2016 United States
Thin films of crystalline materials called perovskites provide a promising new way of making inexpensive and efficient solar cells. Now, an international team of researchers has shown a way of flipping a chemical switch that converts one type of perovskite into another — a type that has better thermal stability and is a better light absorber.
