Perovskite solar cells become even more promising with cheaper materials
Transparent, color solar cells fuse energy, beauty
(Phys.org) —Colorful, see-through solar cells invented at the University of Michigan could one day be used to make stained-glass windows, decorations and even shades that turn the sun's energy into electricity.
Physicists propose a device to capture energy from Earth's infrared emissions to outer space
(Phys.org) —When the sun sets on a remote desert outpost and solar panels shut down, what energy source will provide power through the night? A battery, perhaps, or an old diesel generator? Perhaps something ...
'Photon glue' enables a new quantum mechanical state
(Phys.org) —Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials.
New, inexpensive production materials boost promise of hydrogen fuel
Generating electricity is not the only way to turn sunlight into energy we can use on demand. The sun can also drive reactions to create chemical fuels, such as hydrogen, that can in turn power cars, trucks ...
Self-cleaning, antireflective coating mimicks the structure of moth eyes
(Phys.org) —Porous films, which use similar properties to those seen in moth eyes in combination with nanoparticles, are being developed into robust, self-cleaning antireflective coatings for use on both ...
Nanoscale pillars could radically improve conversion of heat to electricity
University of Colorado Boulder scientists have found a creative way to radically improve thermoelectric materials, a finding that could one day lead to the development of improved solar panels, more energy-efficient ...
Rife with hype, exoplanet study needs patience and refinement
(Phys.org) —Imagine someone spent months researching new cities to call home using low-resolution images of unidentified skylines. The pictures were taken from several miles away with a camera intended ...
Artificial leaf jumps developmental hurdle
In a recent early online edition of Nature Chemistry, ASU scientists, along with colleagues at Argonne National Laboratory, have reported advances toward perfecting a functional artificial leaf.
Charge separation understanding could result in cheaper, more efficient organic solar cells
The goal of making cheap organic solar cells may have gotten a little more approachable with a new understanding of the basic science of charge separation presented in a paper published online today, February ...
'Rogue' asteroids may be the norm
To get an idea of how the early solar system may have formed, scientists often look to asteroids. These relics of rock and dust represent what today's planets may have been before they differentiated into ...
New solar cell technology captures high-energy photons more efficiently
(Phys.org) —Getting the blues is rarely a desirable experience—unless you're a solar cell, that is.
Telescope spies water plumes on dwarf planet Ceres
(Phys.org) —Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt, Ceres.
Solar wind and space dust create new source of water, laboratory study suggests
Water ice is the most abundant solid material in the universe. Much of it was created as the byproduct of star formation, but not all. John Bradley of Lawrence Livermore National Laboratory and his team may ...
