Nanostructures enhance light trapping for solar fuel generation
Future solar cells may be made of wood
Perovskite solar cells become even more promising with cheaper materials
How mighty Jupiter could have changed Earth's habitability
Is Jupiter a friendly planet, Earth's enemy, or perhaps both? For decades, scientists have talked about how the giant gas planet keeps some asteroids from striking our small world, while others have pointed ...
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It's an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn't shine.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 ...
