Nanostructures enhance light trapping for solar fuel generation
First direct observations of excitons in motion achieved
A quasiparticle called an exciton—responsible for the transfer of energy within devices such as solar cells, LEDs, and semiconductor circuits—has been understood theoretically for decades. But exciton ...
Shiny quantum dots brighten future of solar cells
(Phys.org) —A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work by Los Alamos National Laboratory researchers in collaboration with scientists from University ...
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It's an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn't shine.
Organic solar cells more efficient with molecules face-to-face
(Phys.org) —New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor ...
Inspired by moth eyeballs, chemists develop gold coating that dims glare
(Phys.org) —All that's gold does not glitter, thanks to new work by UC Irvine scientists that could reduce glare from solar panels and electronic displays and dull dangerous glints on military weapons.
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.
New study finds 'geologic clock' that helps determine Moon's age
An international team of planetary scientists determined that the Moon formed nearly 100 million years after the start of the solar system (4.470 billion years ago), according to a paper to be published April ...
Negev desert solar field uses water-free robotic cleaning system
Finding the mix: Solar cell efficiency a delicate balance
(Phys.org) —Research from North Carolina State University reveals that solar cell efficiency is based upon a delicate balance between the size and purity of the interior layers, or domains. These findings ...
Revolutionary solar cells double as lasers
Commercial silicon-based solar cells - such as those seen on the roofs of houses across the country - operate at about 20% efficiency for converting the Sun's rays into electrical energy. It's taken over ...
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.
First ring system around asteroid: Chariklo found to have two rings
Observations at many sites in South America have made the discovery that the asteroid Chariklo is surrounded by two dense and narrow rings. This is the smallest object by far found to have rings and only ...
A new object at the edge of our Solar System discovered
The Solar System has a new most-distant member, bringing its outer frontier into focus.
