Researchers increase efficiency of perovskite solar cells. .
2015-11-03 14:31:10| Industrial Newsroom - All News for Today
Scientists at NREL have demonstrated a way to significantly increase efficiency of perovskite solar cells by reducing the amount of energy lost to heat. Theoretical limit of how much solar energy perovskite cells can convert to electricity if hot-carriers are utilized could climb from about 33% to 66%. Paper on the discovery, "Observation of a hot-phonon bottleneck in lead-iodide perovskites," was published online in the journal Nature Photonics, and will also appear in January print edition.

Secrets of the pyramids: Researchers will use muon tomography to search for hidden chambers, construction methods
2015-10-30 20:02:04| Extremetech
Egyptologists have announced plans to use next-generation muon tomography to scan the inside of a number of Egyptian pyramids. Hopefully this will settle questions on how the pyramids were constructed, once and for all.

Spruce Beetles Don't Increase Severity Of Colorado Forest Fires, Researchers Say
2015-10-29 22:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Spruce beetles have often been blamed for increasing the severity of raging wildfires throughout Colorado. While the bugs invade Engelmann spruce and subalpine fir forests and scar the trees they feed on, this destruction is not linked to the occurrence of forest fires plaguing the state, a new study revealed. Within the past decade, spruce beetles have chewed through roughly half a million acres of forests in Colorado. In 2014 alone the beetles reportedly infested more than 87,000 new acres of...
