UNITED STATES: Solar Cell Directly Splits Water For Hydrogen
2008-03-12 14:59:00 Plants, trees and algae do it. Even some bacteria and moss do it, but scientists have had a difficult time developing methods to turn sunlight into useful fuel. Now, Penn State researchers have a proof-of-concept device that can split water and produce recoverable hydrogen."This is a proof-of-concept system that is very inefficient. But ultimately, catalytic systems with 10 to 15 percent solar conversion efficiency might be achievable," says Thomas E. Mallouk, the DuPont Professor of Materials Chemistry and Physics. "If this could be realized, water photolysis would provide a clean source of hydrogen fuel from water and sunlight."Although solar cells can now produce electricity from visible light at efficiencies of greater than 10 percent, solar hydrogen cells - like those developed by Craig Grimes, professor of electrical engineering at Penn State - have been limited by the poor spectral response of the semiconductors used.In principle, molecular light absorbers can use more of the...
Solar Cell Roofing - Energy Producing Shingles That Look Like A Normal Roof
2008-02-27 11:15:00 Solar cell roofing made from solar shingles or solar panels is being increasingly incorporated into the construction of new and existing residential and commercial buildings. Some systems can be hooked in with your conventional electric supply, and can literally make your meter spin backwards so you get a check in the mail instead of a bill.Solar cell roofing made from solar shingles or solar panels is being increasingly incorporated into the construction of new residential and commercial buildings. In many areas, people are choosing to replace their conventional roof with a solar roof when it is time for maintenance. And most of these people would tell you that the long-term value, or short-term increase is resale interest, made it worthwhile.A solar cell roof is called "buiulding integrated", also known by the more complete name "building integrated photovoltaic" (BIPV). BIPV suggests that you would have needed that part of the structure built anyway, and you've chosen to use mat...

Special Coating Greatly Improves Solar Cell Performance
2008-02-24 15:06:00 The energy from sunlight falling on only 9 percent of California?s Mojave Desert could power all of the United States? electricity needs if the energy could be efficiently harvested, according to some estimates. Unfortunately, current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications. A team of Northwestern University researchers has developed a new anode coating strategy that significantly enhances the efficiency of solar energy power conversion. A paper about the work, which focuses on ?engineering? organic material-electrode interfaces in bulk-heterojunction organic solar cells, is published online this week in the Proceedings of the National Academy of Sciences (PNAS). This breakthrough in solar energy conversion promises to bring researchers and developers worldwide closer to the goal of producing cheaper, more manufacturable and more easily implemented solar cells. Such technology would greatly reduce our dependence on ...

CALIFORNIA: Global Solar Energy Achieves 10 Percent Average Solar Cell Effi
2008-02-09 05:23:00 Global Solar Energy (GSE) has announced it is the first in the CIGS thin-film market to achieve an average of 10 percent solar cell efficiency on a flexible/lightweight substrate over several production runs. Global Solar Energy reached the milestone in December 2007, capping off a record year in which the company also manufactured and shipped 4 MW (megawatts) of photovoltaic material powering commercial, government, military and consumer products worldwide."In 2007, we saw a range of economic and environmental factors converge to create a substantial market opportunity for renewable-energy technologies across all facets of the economy," said Mike Gering, CEO of Global Solar Energy . "Government, commercial and consumer demand for renewable-energy products and building materials are growing at a fast pace, thereby putting pressure on CIGS producers and other types of solar manufacturers to deliver high-efficiency products that are flexible/lightweight and lower cost per watt instal...
The Next Generation of Solar Cell
2008-02-05 19:25:00 Conventional solar cells are expensive to produce and inefficient. They are produced with silicon and exotic materials which attempt to boost their effectiveness. In truth, the typical solar cell captures only about 20% of the potential solar energy and, obviously, are completely ineffective after the sun has set.A group from the National Idaho Laboratory is attempting to change that. Their new solar cell design is made up of tiny spiraling antennas printed on a thin film. Each "nanoantenna" is about 1/25 the thickness of a human hair, and made up of common materials. The result is a thin, flexible and cheap solar cell that is 80% effective and can collect energy for hours after sunset.The solar cells collect energy through resonance, the same way a television antenna picks up a signal. The difference is that the nanoantennae is designed on a scale to capture infrared waves. The key is that as the Earth heats up, it gives off infrared waves which can be collected by the anten...
