Breakthrough Solar sheet captures 90 % of sunlight
May 18^th, 2011 at 11:39pm

Some good news for fossil fool share holders and the rest of the anti-progress brigade Wink

Someone is developing this stuff. It's just not here though Sad

Too much money being invested into house renovations research and development

The breakthrough of Solar sheet to captures 90 percent of sunlight

Researchers at the University of Missouri developed a solar sheet device that can capture 90 percent of sunlight or 70 percent more than today traditional solar panels. They have improved the ability of current PV panels to capture a broader range of wavelengths.

Traditional solar powered devices have a weakness in transforming light into electricity and can only capture a small band of wavelengths out of the wide range of wavelengths found in sunlight striking the earth. Researchers used a special thin, nantenna which is moldable sheet of small antennas to capture the wider range of wavelengths. The material will converts heat to electricity that can be used for industrial heat recycling or solar designs which its capable of collecting both optical sunlight and the near infrared band sunlight.

Patrick Pinhero, associate professor of chemical engineering, securing U.S. Department of Energy funding and fund from private investors to working to port the resulting device to a mass-producable design. He also assisted by Dennis Slafer of MicroContinuum, Inc., of Cambridge, Mass., a solar power and alternative energy firm.

In the matters of developing a complete material with electronic devices capable of harvesting heat and light collected by the nantenna, Professor Pinhero worked with researchers at the Idaho National Laboratory and Garrett Moddel, an electrical engineering professor at the University of Colorado. He ambitious to be able to deliver a finished material in the next five years.

Their finding has been published in the peer-reviewed Journal of Solar Energy Engineering.The researchers hope to get more advantage from solar energy is theoretically possible to bring them to the commercial market that can be bought by all people with cheaper price.

Now thats what I've been waiting to hear. Good stuff indeed!

Now watch what happens with an 'Above 50%' Free-Power Source.
This is what I've been holding out for besides knowing that Australia has crap quality Solar Panels compared to Africa and Europe for starters and a lot more expensive too.

...remember when people relied upon WIND to get around the world and many still enjoy doing so.
Now, if only someone puts a big rod up high in Sydney and learns how to 'contain, harness, etc' all those lightning strikes... Wink

I think though, that Australia might show the world how to rejuvenate thelack of fresh water these days and other such stuff.

That would be where the increased wavelength range
would come into it.

There is a mob called, I think Upton Engineering, and they build a "solar tracker", where it mechanically tracks the sun during the day.

Apparently it makes it something like a 1/3 more efficient than a fixed unit.

Put the above solar panels on it and we are talking some serious energy generation

Solar trackers were very fashionable at one stage, but the advice I most often hear these days is to put the money into more panels, which makes sense.

What we really need is better energy storage.

I'm pretty sure those people whose lives aren't 'environmentally' influenced by the Sun as much as others, will eventually create they own "Free Power" from another source. I think there are MANY sources of Free Power to use and harness for the betterment of this world.

...its like a Breath of Fresh Air.

There are things called batteries you know Wink

And do we ignore sunlight and heat energy during the day just because it is not available 24 hours a day ?? It's not an all or nothing solution.

I suppose you shut all of the blinds and turn on all of the lights just because sunlight is not available 24 hours a day.

LOL

The writing has all the style of a fake announcement from India or China. and increasing the efficiency of solar cells from a typical 25-35% to 90% has the feel of fantasy about it. It is the holy grail of soalr PV to get over 50%. Acheiving 90% is almost theoretically impossible being it would need to be totally nonreflective (virtually impossible) and absorb all heat (also impossible).

I tip that it is fake but it would be a truly revolutionary achievement if it is real. It would bring solar PV almost on a par with fossil fuel power (assuming manufacturing costs are affordable and it isnt made out of palladium or unobtainium)

Renewable energy is progressing and it will keep progressing.
I am betting we will look back in 20 yrs time and wonder what all the fuss was about
I am positive about the future and our excelleration away from dirty polluting fossil fuels.
It only takes a few huge break throughs and the dam walls will break..its been the same all throughout human history.
