University of Cambridge Colorful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future. A hybrid form of perovskite - the same type of material which has recently been found to make highly efficient solar cells that could one day replace silicon - has been used to make low-cost, easily manufactured LEDs, potentially opening up a wide range of commercial applications in future, such as flexible color displays....

Carnegie Institution Breaking research news from a team of scientists led by Carnegie's Ho-kwang "Dave" Mao reveals that the composition of the Earth's lower mantle may be significantly different than previously thought. These results are to be published by Science. The lower mantle comprises 55 percent of the planet by volume and extends from 670 and 2900 kilometers in depth, as defined by the so-called transition zone (top) and the core-mantle boundary (below). Pressures in the lower...

Solar Cell Without The Lead

Brett Smith for redOrbit.com - Your Universe Online Using readily available equipment, researchers at from Northwestern University have developed a new type of solar cell based on tin instead of lead perovskite, according to a new report in Nature Photonics. "This is a breakthrough in taking the lead out of a very promising type of solar cell, called a perovskite," said study author Mercouri G. Kanatzidis, an inorganic chemist at Northwestern. "Tin is a very viable material, and we have...

Secrets Of New Solar Material Unlocked

National Renewable Energy Laboratory A new solar material that has the same crystal structure as a mineral first found in the Ural Mountains in 1839 is shooting up the efficiency charts faster than almost anything researchers have seen before—and it is generating optimism that a less expensive way of using sunlight to generate electricity may be in our planet's future. Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) are analyzing the new material,...

Perovskite Solar Cell Laser

Brett Smith for redOrbit.com - Your Universe Online Made from silicon, conventional solar cells are capable of converting 20 percent of the sun’s radiated energy into electricity. A new type of cell made from a mineral called perovskite has been refined to the point of 17 percent efficiency after just two years of development, and new research published in the Journal of Physical Chemistry Letters has shown that these cells are also capable of emitting light energy – in the form of...

Photovoltaic energy conversion offers one of the best means for the future of renewable energy in the world. The efficiency of solar cells depends heavily upon the light-absorbing materials they use. Photovoltaic systems based on lead halide perovskite are a new, revolutionary type of device with efficiencies currently exceeding 16%. However, a detailed description of how these solar cells turn light into electrical current is still lacking. Publishing in Nature Photonics, scientists from...

Scientists have wondered for some time why certain seismic waves travel more quickly through the core-mantle boundary, a thin layer of the Earth's interior that lies between about 1675 and 1800 miles below the surface. Now a new study by Yale University and the University of California, Berkeley sheds light on the mystery by showing how this region behaves under the extreme conditions found so deep in the Earth. The findings, which appeared in the Sept. 24 issue of the journal Science, have...
