Thanks for the info

I am going to try this method using HD aluminum Foil, baking outside, and then using menu size self sticking/sealing non reflecting laminating folding sheets. I found these for a dollar a piece and am excited about them. My question to you learned folks is where can I find these chemicals from? Do you have any links? Also I was hoping to use a car spray gun to spray the sheets instead of screen printing then a mouse sander under a steel plate to vibrate the individual layers. Do you think this will significantly reduce the efficacy? Should I stick with the screen printing?

Water,

Keep us informed of your progress! I would think the screen printing method is used vs spraying maybe because of the viscosity of the ink? Might be too thick to spray and if you try to cut it down like you said, you may lose efficiency of the chemicals to make energy. But I am only guessing. Good luck and I await your results

There is a solar ink out there that is capable of 17.4% efficient cells...

I am unable to find a supplier of the ink a manufacturer sure five star solar or something like that...

I hear you can purchase the ink from japan or something but have yet to come across the ink.

Would be nice to get some help on locating a supplier of the ink.

Thank you all that aid in this search.

http://www.Nanosolar.com and
http://www.konarka.com/
are using inks too.

So I hope we will see soon very cheap solarcells coming out.

Regards, Stefan.

P.S: I just saw, that Nanosolar has a new production facility
near Berlin, Germany where I live.

I will give them a call next week and ask,
if I could visit them and have a few cells and
make a report for overunity.com

I have a question on the dyes being used. I'm pretty sure these dyes have very poor lightfastness. They fade fast in light, especially uv exposure. So are these cells going to have as short of a lifespan as the dye used?

Here's a pdf with good description and instructions.
