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

[ 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...

OPV Cells With High Electric Potential For Portable Electronics
2012-10-11 13:04:17

A new breakthrough in solar technology means portable electronic devices such as e-book readers could soon be re-charged on the move in low light levels and partial shading. Scientists from the University of Warwick, in collaboration with spin-out company Molecular Solar, have created an organic solar cell that generates a sufficiently high voltage to recharge a lithium-ion battery directly, without the need to connect multiple individual cells in series. Modules of these high voltage cells...

Black Silicon Used To Make Solar Cells
2012-10-09 16:01:15

Solar cells convert three-quarters of the energy contained in the Sun℠s spectrum into electricity — yet the infrared spectrum is entirely lost in standard solar cells. In contrast, black silicon solar cells are specifi cally designed to absorb this part of the Sun℠s spectrum — and researchers have recently succeeded in doubling their overall efficiency. The Sun blazes down from a deep blue sky — and rooftop solar cells convert this solar energy into...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
