Solar power in Europe

New technology uses solar energy to super-heat water which is used to drive steam turbines producing electricity. These plants are already in use in Spain. Test plants have been built in north Africa and the Middle East. Naomi Fowler reports on progress in other areas of Europe, including Italy where there is a strong political push for nuclear power. In many countries, current legislation assists existing electricity producers over new technologies.

Robyn Williams: How much of our energy needs can the sun provide in these times of costly oil? In February on this programme Ray Kurzweil from Boston, Massachusetts, predicted new solar technologies that will satisfy all our needs in 20 years if they develop the systems in the same way as IT. Doubters put the figure at between 3 and 5 per cent if we're lucky. In Europe however solar is already moving fast as Naomi Fowler reports

The MIT engineers, experts in optical techniques developed for lasers and organic light-emitting diodes, realized that perhaps those same advances could be applied to solar concentrators.
The result? A mixture of dyes in specific ratios, applied only to the surface of the glass, that allows some level of control over light absorption and emission. "We made it so the light can travel a much longer distance," Mapel says. "We were able to substantially reduce light transport losses, resulting in a tenfold increase in the amount of power converted by the solar cells."

Dow Corning Significantly Increases Solar Panel Production Rates
Midland MI (SPX) Sep 03, 2008 -
Dow Corning has demonstrated a manufacturing process featuring new developmental silicone materials that significantly increases the production rate of solar panels, effectively lowering the cost per watt of solar power. "This technology represents a real step-change in the industry, and will help make solar power a viable and sustainable energy option globally," said Gaetan Borgers, global ... more

Plastic solar or light cells?
Robyn Williams: It's very interesting because when I was in Britain I heard a program on the radio, they used a most wonderful line saying it's 'chips for silicon because plastic is coming'. And the paradox of plastic being able to conduct in this way is counterintuitive, isn't it.
Paul Byrne: It certainly is counterintuitive, and in fact one of the best things about it is you can confuse electricians, because most electricians are quite happy to use plastic covered wires, as we all are. Plastic covers the wires for our toasters, our kettles and so on.
But there are certain plastics that you can design that you can induce to conduct electricity, and if you can do that then you can actually develop devices and have various applications where you can effectively convert electricity into light or light into electricity, and that's very useful.

Prospects for photovoltaics
listen now | download audio
Photovoltaics were developed in 1956 and have since dropped to one-hundredth of their price then. Phil Livingston says major cost reductions are in train in solar thin-film technologies opening up possibilities for a wide range of products and applications.
The push now is to have photovoltaic materials on the surfaces of most buildings, such as the tinting on windows, or the tiles on roofs.

Re: The newest, latest and breaking news about solar energy.
Yes, I agree so much science news is hype maybe ten years before any real invention/pill whatever appears on the market.
Maybe they do this to attract investment?
Yet another project is claiming to be the world’s largest solar power plant, albeit solar thermal.
Quote:
This time it is the company, WorleyParsons, who strangely already knee deep in coal, nuclear and Canadian oil sands, are making the noise. Weird, huh? Maybe they see the writing on the wall, or least figure it is safe to have a bet each way.
Anyhow, according to the Australian Conservation Foundation (ACF) the firm plan on having a 250 Megawatt plant (using the sun’s radiation to power steam turbines) by 2011. It should power the equivalent of 100,000 houses. Though WorleyParsons’ Chief Executive Officer John Grill also reckons "A solar facility a single square kilometre in size could power 50,000 households”. And furthermore they'd like to deliver 40% of the country’s renewable energy by such plants by 2020. (The government want 20% of Australia’s total electricity supplied by renewables by this same period.)

Press Release
Monash Newsline (Monash University)
Thin, flexible and low-cost solar cells roll off the presses
26 February 2009
Video demonstration of solar cell being used as a power source.
Monash University researchers have developed a solar cell which is thin, flexible and can be produced on a mass-scale using the same technology used to print polymer banknotes.
The first of the trial polymer solar cells have rolled off the presses at the Melbourne-based plant of Securency International -- the company responsible for printing Australian polymer banknotes and currency for 26 countries around the world.
Monash researchers Dr Udo Bach and Professor Yi-Bing Cheng are part of the Victorian Organic Solar Cell Consortium -- a team of scientists and industry partners working in collaboration to develop a polymer solar cell that can be printed cheaply and efficiently.
"The film-like solar cells are fabricated on a polymer substrate and are almost as thin as a sheet of paper. The ultimate goal of our work is to develop this alternative solar cell technology to a point where it can compete with conventional photovoltaic technologies already established on the market," Dr Bach said.

More promises or something better?
Do all scientists nowadays need a PR team to ensure funding? Or am I being too cynical.
Quote:
In 1986 solar panels were literally ripped from the White House roof. But political will and financial incentives have reignited the search for efficient, affordable ways to harness the sun’s energy. Two new solar thermal technologies—which focus sunlight to create heat rather than convert it directly to electricity, as photovoltaics do—promise to make solar power practical at vastly different scales.
The SunCatcher solar thermal system, developed by Tessera Solar and built by Stirling Energy Systems at the Sandia National Laboratories’ National Solar Thermal Test Facility, captures solar energy at 31.25 percent efficiency, the highest ever achieved by this technology.
Each of SunCatcher’s 38-foot-wide dishes collects enough heat energy to run a Stirling engine that can then generate 25 kilowatts of electric power.
The system will fulfill two of the world’s largest solar contracts, providing a planned 1,600 megawatts to Southern California by 2014. It improved on its predecessor with a new design that makes each dish substantially lighter and cheaper to manufacture.
