2011 nike free run Breakthrough in solar efficiency by UNSW team ahead of i

The breakthrough involves using hydrogen atoms to counter defects in silicon cells used in solar panels. As a consequence, poor quality silicon can be made to perform like high quality wafers 2011 nike free run.

The process makes cheap silicon “actually better than the best-quality material people are using at the moment”, the head of the university’s photovoltaics centre of excellence, Professor Stuart Wenham, said.

Silicon wafers account for more than half the cost of making a solar cell. “By using lower-quality silicon nike free id 5.0, you can drastically reduce that cost,” he said.

“We’ve been able to figure out what the secret is that enables hydrogen to sometimes work the way people want it to, and sometimes doesn’t.”

At present buy nike free uk, the best commercial solar cells convert between 17 per cent and 19 per cent of the sun’s energy into electricity free shipping nike id. UNSW’s technique nike free shoes canada, patented this year nike free run pink and black, should produce efficiencies of between 21 per cent and 23 per cent.

This has really got the industry very excited, not only in China, but elsewhere as well, said Richard Corkish, head of the university s School of Photovoltaic and Renewable Energy Engineering. Alumni of the school hold senior positions at many of the leading PV producers globally nike free 5.0 v4 blue.

Separately, the UNSW’s Martin Green, dubbed the “father of photovoltaics” for his work to develop and commercialise silicon solar cell technologies, was last week elected into the UK’s renowed Royal Society nike free black and yellow.

Professor Green red nike free, whose work includes overseeing research teams and setting the current 25 per cent conversion efficiency record for solar PV, joins 1,450 of the world’s top scientists as a Royal Society Fellow.

Prices tumble

The price of solar panels has fallen by about 65 per cent in two years, partly due to a huge rise in production in China nike free 3.0 black gold. Australians have been taking advantage of lower prices, with the number of homes with solar panels exceeding 1 million finish line nike free.

The phenomenal growth has caused some casualties in the industry as companies have taken on massive debt to expand supply nike free black red, then struggled with falling prices in saturated markets. Notable among them is the recent debt default by Suntech Power, once the world’s largest solar-panel maker, founded by former University of NSW researcher Shi Zhengrong nike air max free.

Panel prices are predicted to fall much further nike free 5.0 red. European producers predict they will be 60 per cent cheaper by 2020 nike free run black blue. “Based on the technological advances we’re making nike free black white, we think that’s certainly achievable nike air max free shipping,” Dr Wenham said nike free black green.

Eight commercial firms have signed up to be a partner in developing the technology to an industrial scale, including Suntech nike free 5.0 men s, which continues to operate from its base in the eastern Chinese city of Wuxi and has a research unit in Sydney.

“It’s the kind of advance that other people are anticipating is a decade away nike free run trainer,” Suntech R D Australia managing director Renate Egan said. “It is quite a breakthrough.”

Funding

Suntech funded much of the early work, including in China nike free toddler shoes. Suntech has the right to use that (intellectual property) and UNSW has the right to licence the technology to third parties nike free run black red, Dr Egan said.

Funding to help commercialise the technology will total about $15 million over three years, with the UNSW seeking support from the federal government s Australian Renewable Energy Agency for part of that sum.

The annual funding of $5 million equivalent to what bidders last month paid for the half-brother of champion race mare Black Caviar is a lot of money for us nike id free shipping code, Dr Corkish said.

Already worth about $100 billion a year, the solar industry is expected to swell to about $140 billion by 2018 nike free 5.0 trainers, according to estimates published in April by Transparency Market Research nike free black and red.

Installed PV capacity probably surpassed 100 gigawatts, worldwide, in the March quarter, according to the International Energy Agency. Some forecasts project capacity will more than triple by the end of the decade. Australia ranked ninth, with installed capacity of 2.4 GW, at the end of 2012.
