I guess this is a technology that won't be available to the ordinary people.

Same as the, 1/100th thick and 1/10th price compared to ordinary, solar cells developed by nanosolar that didn't make it to the ordinary Joe but to the huge interests.

We live in a very sick world and it's not only the fault of the criminal network but a majority of ordinary people who refuses to openly discuss the most important issues and label them as being racist, politically incorrect, conspiranoic, boring, etc.

They'll be on a shelf in the back room of your local coal/oil company soon, collecting dust.

They All Work in the Dark

Gentlemen,

ALL solar panels work in the dark. Especially the standard, silicon wafer type. Look at their specifications and the spectra of "light" they are sensitive to. The sensitivity peaks at 900nm, which is way off in the infra-red range. Bedini and I ran all of these experiments back in 2004. A "solar panel" will put out continuous power in a dark room if placed near a hot piece of black cast iron, like a wood stove. The main danger is that the panel will crack if it gets too hot, but the heat can be managed. John also has shown me a 1/8th inch thick piece of black plastic he got that transmits infra-red, but blocks all visible light. It looks absolutely opaque to the naked eye unless you hold it up to the sun, which looks like a deep red circle. If you place this sheet of black plastic over a solar panel in the direct sun, the panel instantly produces 20% more voltage! I have done the experiment myself. The reason this works is obvious. The black plastic transmits all of the heat straight through and absorbs all of the visible spectrum and re-emits that energy as even more heat.

I hope this helps.

Thank you Peter

Also, this is the compound behind invention - gallium arsenide nitride - New photovoltaic material could deliver twice the solar power

Pretty interesting comments. From my understanding, "Photons" would be the desired energy source for photovoltaics, but thermal does play an important role with them as well. The "conventional wisdom", as i understood it, regarding PV's is that increased temperature generally lowers efficiency, not improves it.

The recent discovery from Stanford U. for considerably more efficient SILICON-based panels (important in that the material is not expensive, although this particular coating technology is still in its infancy), is very interesting imo. Here is a cheap material that can create panels that are double or more the current efficiency, for a comparatively low cost. Because it is important to note, that PC memory and processors costs thousands each when they first came out; once the R&D is paid for and the manufacturing techniques understood... the only major decider for cost is manufacturing volume. And we do now mask IC's in nano scale: So this technology should be do-able and engineer-able within a couple years of being....

SERIOUSLY WORKED ON AND NOT IGNORED.

Solar cells thinner than wavelengths of light hold huge power potential

Quoted from the end of that "Stanford U. News" magazine article:

"The project was supported by funding from the King Abdullah University of Science and Technology, which supports the Center for Advanced Molecular Photovoltaics at Stanford, and by the U.S. Department of Energy."

solar panels

This is one of the most efficient solar concepts ever that never got
produced, of course.

Alvin Marks - Lepcon& Lumeloid -- 90% efficient solar-electric power conversion -- articeles & patents

Anyway, the test out at Bedini's is very interesting. Blocking all the
visible light increase the output.

I don't believe the amount of heat is increasing by putting on the filter.
It lets the panel see a specific narrow band of far IR that is optimum.
Any light energy it receives will have to be reemitted. The increase by
blocking the visible light spectum INSTANTLY caused the output to
crank up.

This looks like the original article posted by Ash.

So what exactly

Was this black plastic? Was it just black plexiglass, or polycarbonate, or was it some 'special' plastic, especially made for this purpose?Jim

My solar panels seem to work better when warmer.

Quite a few panels have been built that showed well over 40% light of some kind to electricity conversion ratios but none have made it to market. Some of them were as far back as 2001. All bets are off on anything thats over 20%. Thats starts actually competing with true coal costs. 40% beats advertised coal prices. And natural gas is getting cheaper by the day, at least on the production side. So they'll have the power soon. Thats in the US anyway.
