New 'tunable' semiconductors will allow better detectors, solar cells Atlanta HA (SPX) Apr 16, 2014 - One of the great problems in physics is the detection of electromagnetic radiation - that is, light - which lies outside the small range of wavelengths that the human eye can see. Think X-rays, for example, or radio waves. Now, researchers have discovered a way to use existing semiconductors to detect a far wider range of light than is now possible, well into the infrared range. The team h ... more |  |
Shiny quantum dots brighten future of solar cells Los Alamos NM (SPX) Apr 16, 2014 - 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 of Milano-Bicocca (UNIMIB), Italy. Their project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight. ... more |  |
Scientists open door to better solar cells, superconductors and hard-drives Hamburg, Germany (SPX) Apr 16, 2014 - Using DESY's bright research light sources, scientists have opened a new door to better solar cells, novel superconductors and smaller hard-drives. The research reported in the scientific journal Nature Communications this week enhances the understanding of the interface of two materials, where completely new properties can arise. With their work, the team of Prof. Andrivo Rusydi from the ... more |  |
Better solar cells, better LED light and vast optical possibilities Oslo, Norway (SPX) Apr 16, 2014 - Changes at the atom level in nanowires offer vast possibilities for improvement of solar cells and LED light. NTNU-researchers have discovered that by tuning a small strain on single nanowires they can become more effective in LEDs and solar cells. NTNU researchers Dheeraj Dasa and Helge Weman have, in cooperation with IBM, discovered that gallium arsenide can be tuned with a small strain ... more |  |
Let the Sun Shine In: Redirecting Sunlight to Urban Alleyways Washington DC (SPX) Apr 16, 2014 - In dense, urban centers around the world, many people live and work in dim and narrow streets surrounded by tall buildings that block sunlight. And as the global population continues to rise and buildings are jammed closer together, the darkness will only spread. To alleviate the problem, Egyptian researchers have developed a corrugated, translucent panel that redirects sunlight onto narro ... more |  |

Microgrid Solar Completes Largest Single-Building Solar Installation on any Missouri School St. Louis MO (SPX) Apr 14, 2014 - Placing 386 solar panels on the science building at MICDS was no small feat for Microgrid Solar. This is the largest solar array installation on one building for any Missouri school. Due to the synthetic shingles on the new LEED certified McDonnell Hall, a group of engineers pioneered a system to allow the microinverters to be installed so that the students can carefully monitor how the we ... more |  |
Clean Energy Collective and RGS Energy to Deploy First Community-Owned Solar Facilities in Massachusetts Boulder CO (SPX) Apr 14, 2014 - The community solar developer, Clean Energy Collective (CEC), has selected RGS Energy as the general contractor for the construction of the first community-owned solar facilities located in the Commonwealth of Massachusetts. RGS Energy, a nationwide leader of turnkey solar energy solutions for residential, commercial, and utility customers, will provide engineering, procurement and constru ... more |  |
Sunlight generates hydrogen in new porous silicon Philadelphia PA(SPX) Apr 11, 2014 - Porous silicon manufactured in a bottom up procedure using solar energy can be used to generate hydrogen from water, according to a team of Penn State mechanical engineers, who also see applications for batteries, biosensors and optical electronics as outlets for this new material. The surface area of this porous silicon is high," said Donghai Wang, assistant professor of mechanical engine ... more |  |
Stanford scientists model a win-win situation: growing crops on photovoltaic farms Stanford CA (SPX) Apr 11, 2014 - Growing agave and other carefully chosen plants amid photovoltaic panels could allow solar farms not only to collect sunlight for electricity but also to produce crops for biofuels, according to new computer models by Stanford scientists.
