Guides for increasing the efficiency of organic solar cells
AIST researchers have calculated the theoretical limit of the photoelectric conversion efficiency of organic solar cells, which have gained attention as a new generation of solar cells.
Image: NEOWISE celebrates first month of operations after reactivation
(Phys.org) —In its first 25 days of operations, the newly reactivated NEOWISE mission has detected 857 minor bodies in our solar system, including 22 near-Earth objects (NEOs) and four comets. Three of ...
It's hot... super hot: Finding answers around the sun
(Phys.org) —Astronomers have collectively puzzled over two working theories for a conundrum involving the sun that have been discussed in Astronomy 101 classes for decades: Why is the sun's corona (the ...
Researchers shed new light on dark energy, cosmic speed-up
In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion.
Inspired by nature
To maximise the efficiency of solar cells of the future, physicists are taking a leaf out of nature's book.
Low-priced plastic photovoltaics
Photovoltaic devices, which tap the power of the sun and convert it to electricity, offer a green—and potentially unlimited—alternative to fossil fuel use. So why haven't solar technologies been more ...
Radio observatory helps identify missing link between solar storms and radio bursts
(Phys.org) —New research by scientists at Trinity College Dublin, University College London, and the University of Hawai'i, published online in Nature Physics, has shown for the first time a direct link b ...
Spectral analysis reveals Moon might have had water when it was formed
Cosmic turbulences result in star and black hole formation
Just how stars and black holes in the Universe are able to form from rotating matter is one of the big questions of astrophysics. What we do know is that magnetic fields figure prominently into the picture. ...
One-of-a-kind spectrometer reads vibrations between atoms to find structures of molecules
A Rice University laboratory has improved upon its ability to determine molecular structures in three dimensions in ways that challenge long-used standards.
Sounding rocket to study active regions on the sun
(Phys.org) —At NASA's White Sands Test Facility in Las Cruces, N.M., a sounding rocket is being readied for flight. Due to launch on Aug. 8, 2013, the VERIS rocket, short for Very high Resolution Imaging ...
The heart of space weather observed in action
Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field ...
Solar tsunami used to measure Sun's magnetic field
(Phys.org) —A solar tsunami observed by NASA's Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun's magnetic field.
DNA constructs antenna for solar energy
Researchers at Chalmers University of Technology have found an effective solution for collecting sunlight for artificial photosynthesis. By combining self-assembling DNA molecules with simple dye molecules, ...
