MicroLink Devices, a leader in high-efficiency solar cell technology, announced the development of a lightweight, flexible, high-efficiency solar sheet suitable for powering small electrical equipment off the power grid. The sheet has a conversion efficiency of 29%, generates up to 9.25 watts in a 320 square centimeter active area, and weighs 230 grams per square meter. Niles, Illinois (PRWEB) February 06, 2013 MicroLink Devices, Inc., (http://www.mldevices.com) a Niles, Illinois-based...

Geometric pattern maximizes time light is trapped in solar cell The sun´s energy is virtually limitless, but harnessing its electricity with today´s single-crystal silicon solar cells is extremely expensive – 10 times pricier than coal, according to some estimates. Organic solar cells – polymer solar cells that use organic materials to absorb light and convert it into electricity – could be a solution, but current designs suffer because polymers have...

Nanowires More Efficient Than Solar Cells
2013-01-18 19:23:18

Lee Rannals for redOrbit.com — Your Universe Online A team from Lund University in Sweden wrote in the journal Science about how nanowires could eventually make way for more efficient solar cells. Scientists have been studying solar cell nanowires more and more, and until now, the dream figure was ten percent efficiency. However, the Swedish researchers were able to report an efficiency of 13.8 percent. Nanowires are made of the semiconductor material indium phosphide and work...

Instrument Developed To Toss Out Unusable PV Wafers
2013-01-15 16:24:31

National Renewable Energy Laboratory (NREL) Silicon wafers destined to become photovoltaic (PV) cells can take a bruising through assembly lines, as they are oxidized, annealed, purified, diffused, etched, and layered to reach their destinies as efficient converters of the sun's rays into useful electricity. All those refinements are too much for 5% to 10% of the costly wafers. They have micro-cracks left over from incomplete wafer preparation, which causes them to break on the...

Multi-Junction Solar Cell To Break Efficiency Barrier Designed By NRL
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...

Word of the Day
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
