DIY Solar Cells through screen printing

I was wondering if anyone has seen the "plans" offered by fuellessamerica.com on producing solar cells cheaply and at home through screen printing. They claim efficiencies of 12-14% can be achieved. I know most solar cells are screen printed, but I know the doping can be difficult. Has anyone seen/done this? I have seen the American patent held by a Japanese company that outlines the process. I didn't have much time to peruse it however. I did notice they were using correct terminology, but it was obviously geared towards commercial enterprise. Any thoughts?

i know how to screen print, i just dont know what type of ink to be used in SOLAR CELL PRINTING?

You're looking for anthrocyanins.
These are fairly common pigments in plants, but if you have the stuff to do organic synthesis reactions, you can make them at home.

There's also some stuff about quinones being used, but they tend to be less stable.

Hi,
May be following links shall be useful to your needs...

I am very inquisitive to know the further progress. Your knowledge sharing shall be well appreciated.
Cheers!!!
I just thought I would pass on some information you might like to know, the screen printing of cells is possable and really cheap. You are not sure of the actual ways available to get the nitrogen onto the plate, or the crystals to form most effeicently and all that. Well I have a plotter (like a printer but it uses felt tip pens and other like pigment generating devices to make a print and by using a adjustable ball type pen I am able to get the elements onto the acitate (a type of silicon plastic, very flexable but with the dielectric properties of glass in a super thin materal) which will go threw the plotter which already handles flat materals easy. and by using the seprate chemicals in seperate ball pens after layering the ones for the selidium layer, I made a pen that fits te plotter which produces a small arc of plasma which interacts with the layers by burning off the "fuel" (I use hydrogen sillate) which produces the tems needed for a very short time to get the crystal process to happen on the plate. Well now your likely wanting to now why I am telling all of you this? It is because of this plotter I have made that a friend was so interested in (he happens to be a physics major) that he had a brilliant idea on how to make a stable "paint" that can be screen printed onto thin aluminum foil then plasma flashed to crystalize into a usable cell with a 65% efficency, he applied for a grant and is currently very close to startingmas production of a super cheap solar cell very near to the currently "grown" cells at a cost of a fraction of cells currently available. Today cells are costly because of the process to grow them and get more than 60% effeciency from them at a cost of about 50 cents a millawatt on a very fragile glass where this new process will bring the cost down to about 25 cents a watt (that figures out to about a differance between a panel to produce 100 watts at 12 volts at about 350 dollars to a much thinner, flexable, 23% smaller, panel to produce the same to about 6 dollars) So if you still wish to try making your own cells, thats fine, this is how things are discovered, but keep in mind that within 3 to 6 months, these new cells will come onto the market and make solar finally a economically way to obtain power from the sun. As far as I can figure, for my house and the fact that it is 100% electric (hot water, cooking, heat, etc.) and with all the computers I have, and that I am veery fortunate to have a very large roof facing the sun for a large part of the day, for about one thousand dollars, I can line my roof with the new cells (well thats materal cost and no labor) that will supply my home with power and enough to pump back into the current electric system for no sun times, that I couls come super close to breaking even and if the sun is more than usual for this area, actually be ahead on my total electrical costs each year. Now the availablity at first for these new cells will be hard to get because there is already a huge list of customers wanting cells when manufacturing begins, and it will take time for the manufacturing to expane to handle the orders. But within the next two years we will be seeing a huge amout of people and companies using solar power and within five years it will supply the majority of our power needs. The technology is there and it is simply a short wait befor it becomes available to all. But keep experimenting, because it is because of people like you all that has made this all possable. If you would like to work on something that needs work here is a good thing to work on. Today, cars can operate on hydrogen gas with a small upgrade. This planet has a unimaginable supply of hydrogen, the problem is getting it to a usable form, currently we can get hydrogen by sending direct current threw water which produces hydrogen, but it is super ineffecient, so experiment with new ways to seperate water into its gas forms, this is where our future will profit most.
Actually... i can see the aluminum foil being a good idea, but i'd question whether your friend has a solar cell or a sun catalyzed battery.

Using aluminum seems like you'd get more of a solid state electrolyte, which acts as a battery. If it's doing this, the aluminum should eventually degrade (probably to aluminum oxide).

That said, depending on how long it takes, and the amount of energy the cell provides before needing to be replaced, that could still be a useful thing.

I was just replying to a comment above, and read through your comment again. It has been some time, are there updates?
Hi, just wondering how much further you have progressed.

Hello,
Is your friend successful in making them? Please let me know as I want ot convert my home to solar energy ASAP.
