Solar energy turns organic

(Nanowerk News) Cheap and efficient conversion of solar energy into electricity could help combat global warming and the shortage of fossil fuels. However, the high production cost of electricity from silicon-based solar cells has limited the use of the technology. Low cost solar cells with high cell performance are highly desirable and organic solar cells could be the answer. They are easy to make from inexpensive organic materials and, unlike inorganic solar cells, are lightweight, flexible and colourful.

Researchers Improve Solar Cell Performance

Vegematic writes "Researchers at MIT have improved solar collectors using dyes. They just increased their performance results by a factor of 4. These paint-on materials can increase the power obtained from existing solar cells by a factor of over 40 without needing to track the sun. 'By collecting light over their full surface and concentrating it at their edges, these devices reduce the required area of solar cells and consequently, the cost of solar power. Stacking multiple concentrators allows the optimization of solar cells at each wavelength, increasing the overall power output.' There is also a shorter FAQ available."

Researchers Produce Best-Yet Dye-Based Solar Cells

In work that may help solar panels become a more viable source of mainstream power, a research group has created a dye-based solar cell with a high efficiency and high stability, and that lacks the volatile chemicals used in similar cells. This is a combination so far lacking in the newest solar-cell prototypes.

High-Efficiency, Flexible, High-Stability Solar Cells

Nanotechnology-based hybrid nanocrystal inorganic thinfilm photovoltaics combine the best features of solar cells constructed from bulk thin-film silicon and from polymer solar cells. The colloidal nanocrystal (NC) cell technology offered here allows the production of air-stable solar cells processed using solution phase methods. The technology simplifies fabrication under ambient conditions, thus expanding the range of flexible or conformal substrates that can be used.

First Solar (FSLR): Encourage profit taking/shorting here - FBR

FBR is out with a negative call on First Solar (NASDAQ: FSLR) and SunPower (NASDAQ: SPWR) after Solar Electric Power Association (SEPA), an industry association bridging the solar and utility industries, announced yesterday theresults of its survey of utility companies (titled:"Utility Solar Electricity Market Survey"). Summary: (a) projected PV installations of ~2 GW, on aggregate, over the next three to five years in solar portfolio, versus >3 GW for CSPs across the U.S. utilities; (b) possible paradigm shift, with utilities owning the plants and PV suppliers becoming only turn-key provider (if ITC is given to utilities instead of third parties).

Our Solar System: An Island of Calm in a Violent Universe (and it's special, too)

We humans like to think we're special, but astronomically speaking we've been shot down quite severely and humbly put in our place. We're not at the center of our solar system, nowhere near the center of our galaxy and certainly not at the center of the universe. But now comes great news for the human psyche from scientists trying to explain solar system formation. As far as solar systems go, we have thought ours was just average and that all solar systems were like ours. But in looking at the 300 plus extrasolar planets that have been discovered and the systems they are in, none so far are anything like our home solar system. In fact, say scientists at Northwestern University, we may be special after all. In a study using computer simulations (this is the week for computer simulations, see here and here), researchers ran more than a hund

New Efficiency Benchmark For Dye-sensitized Solar Cells

Scientists have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells. This breakthrough in efficiency without the use of volatile organic solvents will make it possible to pursue large scale, outdoor practical application of lightweight, inexpensive, flexible dye-sensitized solar films that are stable over long periods of light and heat exposure.

In a paper published online June 29 in the journal Nature Materials, EPFL professor Michael Graetzel, Shaik Zakeeruddin and colleagues from the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells. This breakthrough in efficiency without the use of volatile organic solvents will make it possible to pursue large scale, outdoor practical application of lightweight, inexpensive, flexible dye-sensitized solar films that are stable over long periods of light and heat exposure, according to Eurekalert, the news service of the American Association for the Advancement of Science.

Nanowires make bendy solar cells

Highly bendable "dye-sensitized" solar cells made from zinc oxide nanowire photoelectrodes on plastic substrates have been developed by researchers in Singapore. The devices, which conserve their photovoltaic properties even when greatly bent, could find use in a variety of flexible and portable applications, such as solar-cell mobile phone chargers, clothes and umbrellas.

World's Largest Solar Plants Planned In California

Pickens writes "Two photovoltaic solar power plants will be built in San Luis Obispo County in California, covering 12.5 square miles, that together will generate about 800 megawatts of power, the latest indication that solar energy is starting to achieve significant scale. 'If you're going to make a difference, you've got to do it big,' said Randy Goldstein, the chief executive of OptiSolar. OptiSolar will employ enough of its amorphous silicon thin-film solar panels at its Topaz Solar Farm project to generate 550 MW. Meanwhile, SunPower will install mechanical tracking for its more expensive 250 MW-worth of crystalline silicon photovoltaics at High Plains Ranch II in a bid to boost their efficiency by 30 percent from following the sun across the sky.
