I thought 5% was good for a solar panel.

Their has been some major breakthrough with solar pannels. They have created a crystalline fluid that can absorb the entire spectrum of visible light, but they are having problems getting it into a crystalline structure for opimum efficency. They rated the efficentcy of about 80%

I couldnt think that it could be done, but thunderchild has a bigger signature then what I had!

Wow.

Where's the rest of the video?
I hate it when they only include half of it!

Didn't you hear the "... ...could be... ..." at the start of the video.
Nano Solar is trying for almost several years now, so don't expect it tomorrow

I saw that video something like 5 years ago... ...
Former UniSolar now ECD Ovonics is already producing flexible thin film PV cells for several years but their efficiency can't beat cristalline PV cells (for now).

That's bad

When I was busy with solar panels some years ago the efficiency was around 10 to 12% for cristaline cells and around 8 to 9% for thin film cells.

the 80% is 80% of standard solar panels

**Krumlink** · 9th September 2007, 08:36 PM

That is what they meant. They are 80% efficent as compared to todays solar panels.
The sun beats out thousands of watts of power per meter (I think around 2000 watts it was), so to capture 5% of it that would be 100 watts. 10% is 200watts. 80% is 1600 wattts. Thats alot of POWER!!!

NOTE: The wattage would be for a meter squared solar panel, so one meter by one meter to get these wattages.

So you mean only 4%? (assuming todays panels are 5%).

Certainly nowhere near 80% of the light energy they receive!

**Krumlink** · 9th September 2007, 10:12 PM

Yeah, I hope you know what 80% of 5% is

One can find a lot of numbers on the net and in literature about "sunpower" ...

Since insolation is different for all locations on the planet, the nominal power of a solar panel is given for a 1000W/m² insolation perpendicular to the panel.
That sunpower you will get on the equator at noon
