2013-01-14 11:50:25

U.S. Naval Research Laboratory U.S. Naval Research Laboratory scientists in the Electronics Technology and Science Division, in collaboration with the Imperial College London and MicroLink Devices, Inc., Niles, Ill., have proposed a novel triple-junction solar cell with the potential to break the 50 percent conversion efficiency barrier, which is the current goal in multi-junction photovoltaic development. "This research has produced a novel, realistically achievable, lattice-matched,...

Berkeley Lab's Advanced Light Source Uncovers New Path To More Efficient Organic Solar Cells
2013-01-07 12:42:39

DOE/Lawrence Berkeley National Laboratory Why are efficient and affordable solar cells so highly coveted? Volume. The amount of solar energy lighting up Earth's land mass every year is nearly 3,000 times the total amount of annual human energy use. But to compete with energy from fossil fuels, photovoltaic devices must convert sunlight to electricity with a certain measure of efficiency. For polymer-based organic photovoltaic cells, which are far less expensive to manufacture than...

Peel And Stick Solar Panels Unveiled At Stanford
2012-12-21 10:30:15

Brett Smith for redOrbit.com - Your Universe Online Solar cells provide emissions-free power at a relatively low cost, but for all their benefits, the cells still have one major drawback — they are stiff, bulky and therefore limited in their application. According to a paper in the latest edition of Scientific Reports, however, Stanford engineers have just discovered a potentially revolutionary solution to this predicament — peel-and-stick solar cells. Until now,...

Big Boost To Solar Power Given By Tiny Structure
2012-12-07 16:29:15

Princeton University, Engineering School Princeton researchers have found a simple and economic way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power. The researchers, led by electrical engineer Stephen Chou, were able to increase the efficiency 175 percent by using a nanostructured "sandwich" of metal and plastic that collects and traps light. Chou said the technology also...

Flexible Silicon Solar-cell Fabrics Could Soon Be A Possibilty
2012-12-07 12:12:17

Penn State For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that has been shown to be scalable to many meters in length. The research opens the door to the possibility of weaving together solar-cell silicon wires to create flexible, curved, or twisted solar fabrics. The findings by an international team of chemists, physicists, and engineers, led by John Badding, a professor of chemistry at Penn State University, will be posted by the...

EPFL scientists are producing hydrogen from sunlight, water and rust - They're paving the way for an economic and ecological solution for storing renewable energy How can solar energy be stored so that it can be available any time, day or night, when the sun shining or not? EPFL scientists are developing a technology that can transform light energy into a clean fuel that has a neutral carbon footprint: hydrogen. The basic ingredients of the recipe are water and metal oxides, such as iron...

Scientists Make Solar Cells Out Of Carbon
2012-11-01 04:39:42

[ Watch the Video: Stanford Scientists Create All-Carbon Solar Cell ] Lee Rannals for redOrbit.com - Your Universe Online Scientists from Stanford University report in the journal ACS Nano that they have created the first solar cell made entirely out of carbon. Creating solar cells from carbon could be a promising alternative to the expensive materials used in photovoltaic devices today. "Carbon has the potential to deliver high performance at a low cost," said study senior author...

Word of the Day
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
