Who is the best producer?
Thank you and kind regards, Stefano

OK, is not the right group to discuss seriously about photovoltaic.....

You might start to ask serious questions first - a typical GIGO problem.
I guess the best one is Sanyo - they have cells which are 10 percent better than others (HIT has a transparent rear electrode and thus may use light reflected from the back). They cost 5 percent more for manufacturing, but they are sold for 15 percent more.

Sorry, my post was not very good: I've read that there are new cells without silicium, is that true? I'm searching informations on this type of cells, who produce that kind of cell? Are they really "Silicium-free"?

There are very old cells - some call them leaves ;-) There are many different materials, such as GaAs - not new either, but maybe always remaing the material of the future.

Don't know whether you actually look for Si free or just almost Si-free (thin coating only). Maybe you'd want to check the basics first and then think once again what you might have read and where this was.

I suppose you could start here: http://en.wikipedia.org/wiki/Solar_cell http://en.wikipedia.org/wiki/Photovoltaics http://www.google.com/search?hl=en&q=non+silicon+photovoltaic&btnG=Search

They also use silicon, both crystalline and amorphous.
Assessing the "best" producer of non-silicon solar cells is difficult, since the vast majority of solar panels in the world are crystalline silicon and the vast majority of thin-film panels are amorphous silicon. Not to mention that "best" is a subjective term. If pressed to answer the question as-asked I suppose I would say First Solar, primarily because they seem to be the ones actually producing non-silicon thin-film solar modules in the highest volumes.
