The use of infrared photovoltaic cells has also been proposed to increase efficiencies, and perhaps produce power at night.[citation needed]

He's only using far IR because he can't even envision how to rectify anything any shorter wavelength. Not that he's done far IR either, but he's hoping he can pull it off.

Note weasel words: "has been proposed", "perhaps"

Yeah thats the thing You claim to know so much about Solar panels yet you won't provide a possible conversion rate from 90%+ collection of the light compared to 20% collection in conventional solar panels

I'm trying to parse that but I can't get it to resolve logically. Let's try again. You don't have a freaking clue what the collection rate for a solar cell is, because they don't typically publish that number. What you have for a photovoltaic cell is a conversion efficiency. Which is the electrical energy output divided by the light energy input, multiplied by 100, for the rated load. Which also takes into account losses in the diodes and in the conducting parts.

A conversion efficiency is not a collection efficiency. No matter how many times you misuse the two.

What would you estimate the amount of power increase from the conversion efficiency considering they are taking in 90%+ light compared to a meager 20% light with conventional panels.

I'm starting to think you're a paid Big Energy dis-info

You can't estimate it because you don't have the data you need. When he makes a power producing device, you will know. If he can. Because you don't have a clue what sort of losses you're going to get. He's first got to make nantennae with working diodes that can rectify THz band EM. Efficiently. And without leaking. At least not very much. If he can get one AT ALL, then you've got to worry about other parameters on that diode, like the reverse breakdown voltage. But first he's got to get it to go at all.

If this is on the level then he has sealed his fate. It will not be a month until he has a bad accident or the lab burns up or some other such crap puts a stop to this. Patrick Pinhero, remember that name. I created a Google News alert for that name. If there is any thing to this then I give it a month until something puts a stop to it.

4 TIMES MORE LIGHT. I'm Sure it most be at-least twice as efficient As Conventional Solar Panels.

Funny how you ignored the Idea of Water cooling the Solar panels from Underneath and Converting the Heat into Steam Power.

You should Give an estimate since you know so much about Solar panels i'm sure you can give a rouge estimate of the energy efficiency you're just playing coy.

Apparently his research is done under the Government So i can say he probably won't be attacked they will most likely use this for military and or space applications first if it works.

But to the point i think they will supress the technology if it works from the Public Because they know it will Provide too much free energy.

Oh yes and what do you think of the Idea of a water cooling system that pumps water to the Solar Panels Through the steam power created by the heat coming off of the Solar Panels/sheets.

Like say is it possible you think for a device behind the Solar panels that has water in it and that device has water in it The water heats up in the chamber creating steam-power from the water heating up through whatever process steam engines collect power through a turbine right?

This will make it a very realistic idea look at the heat produced by the new magnification process.

The company claims its magnifying glasses intensify the sun’s rays 2000 times onto photovoltaic cells, which increases the heat to 3300 degrees Fahrenheit. While such heat will fry silicon in no time, the company says its electronics actually stay just about six degrees above ambient temperature thanks to special heat convection and generous spacing of the electronics.

Reverse currents waste power and can also lead to overheating of shaded cells. Solar cells become less efficient at higher temperatures and installers try to provide good ventilation behind solar panels

*sigh* How in the name of Thor do you get "4 TIMES MORE LITE!!!11"? You can't compare conversion numbers and collection numbers. Well, in your world where the data doesn't really count and you can just pick any number you like to repeat over and over, I guess you can. It's meaningless, but hey.

You can't get past two digit numbers not being comparable because they aren't describing the same thing. Why sully your mind with Mollier charts?

Let him fab a few rectifiers that work, I'll give you numbers. So far he's mostly simulating his antennas - when he gets around to making some devices with rectifiers that work at 10-20THz, we'll see.

Ok maybe you can't read the article properly

A scientist at the University of Missouri-Columbia has developed a flexible solar sheet that can capture more than 90% of light.

Today's solar panels typically collect only 20% of the available light. Patrick Pinhero, associate professor in the MU Chemical Engineering Department, said he a way to extract electricity from the collected heat and sunlight using special high-speed electrical circuitry in collaboration with colleagues t the University of Colorado.

Wikipedia- Solar Panel

Sunlight conversion rates (solar panel efficiencies) can vary from 5-18% in commercial products, typically lower than the efficiencies of their cells in isolation. Panels with conversion rates around 18% are in development incorporating innovations such as power generation on the front and back sides.[citation needed] The Energy Density of a solar panel is the efficiency described in terms of peak power output per unit of surface area, commonly expressed in units of Watts per square foot (W/ft2). The most efficient mass-produced solar panels have energy density values of greater than 13 W/ft2.

I suppose this one makes you made ^^^ because it upsets your dis-info agenda.

Ryan has trouble keeping track of the difference between heat and temperature, as do you, but you might get out the dictionary and look up the implications of the word "ambient" in the above reference of yours - I hesitate to call "Wired" a cite (sorry, David) - but at six degrees above ambient you're not going to get steam. And again, there really doesn't seem to be any need to whup out a Mollier chart and discuss turbine efficiency with low quality steam.

Reverse currents waste power and can also lead to overheating of shaded cells. Solar cells become less efficient at higher temperatures and installers try to provide good ventilation behind solar panels

Ah, and here lies one of the several rubs that your champion will face. THz diodes are notoriously leaky and have really high reverse currents as a rule. At ambient. Hell, it's not easy to get a good 100GHz diode, much less a 20THz one.

No, it makes me sad because you're thinking Tom's Hardware is irrefutable because you want them to be, and can't or won't read the actual paper. Well, there's the schadenfreude part of you repeating it over and over and not being aware of what you're talking about, so it is sort of entertaining.

Solar panels use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The structural (load carrying) member of a module can either be the top layer or the back layer. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The conducting wires that take the current off the panels may contain silver, copper or other conductive (but generally not magnetic) transition metals.

Now, if you want to skip the pv's and go right for solar concentrators running Sterling engines, you can get up to 30,35% efficiency RIGHT NOW. Off the shelf. That's way better than bulk PV. Conversion efficiency - not capture efficiency. Off the back of the generator, 30+%.

Of course, if you had PowerChips, another nano idea that was a big bust, you could collect solar thermal power right at Carnot efficiency. But they couldn't make them work outside the lab. Alas.

Bees smell fear, and the human head weighs about eight pounds. The bandgap energy for silicon is about 1.18 eV, at 275K.

Yes see there will be several Dis-INfo agents who will come on here and try to dis-credit the claim. They want to conceal this because it will destroy Big Energy and the Oil Companies.

Some people would fare better if they held off on the emotive statements when posting REAL tech.

Because I almost clicked can due to the lack of info in the OP and the abundance of conspiracy, but luckily I read the link.

Oh well.

This.

If information is the crucial point, profit is not.

What stops free information? Profit.

The internet, if nothing else, has proven that is is a gateway for Freedom of Information. The only thing stopping people releasing information, IRC, Usenet, Blogs, Youtube, Whatever your choice you are not restricted until it spreads.

Once it spreads you are NOW incapable of stemming the flow.

So, either the people with tech that only sell it are after profit, OR they don't have it.

I have never read a falsehood on tomshardware, so with that I give it credit.

And I know there are existing solar panels that operate far more efficiently than current photovoltaic cells.

Sell it, lose it - give it away, its forever.

really ? sow what do you say to all the people who claim to have patented ` over-unity ` devices ?

Nah sorry but these threads come around all of the time with new so called breakthroughs and they always end with someone looking for funding.Just another cheap energy scam.
If the tech is there then they should just release the info of how it works and how its made.

Wow! For me this demonstrates the awesome power of thought -- for the last month or so I've been thinking a lot about solar technology and how the next generations of it will be incredible sources of energy. So glad to see that the future is coming!!
