Switchable material could harness the power of the sun—even when it's not shining
It's an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn't shine.
Energy breakthrough uses sun to create solar energy materials
In a recent advance in solar energy, researchers have discovered a way to tap the sun not only as a source of power, but also to directly produce the solar energy materials that make this possible.
First sightings of solar flare phenomena confirm 3-D models of space weather
Scientists have for the first time witnessed the mechanism behind explosive energy releases in the Sun's atmosphere, confirming new theories about how solar flares are created.
Researchers improve performance of III-V nanowire solar cells on graphene
(Phys.org) —Imagine a field of small wires—standing at attention like a tiny field of wheat—gathering the Sun's rays as the first step in solar energy conversion.
Unlocking secrets of new solar material
