They are different metals.   I was going to offer to email the PDF to
everyone but I'll do one even better.  I'll have it available to dl off
my 1&l account by the end of the weekend and post back.

Still not sure what the point is. You don't make pv from etchings or
silkscreening, you make them from growing silicon crystals and doping
the junctions with boron and phosphorous.

Is PV different than solar?  There are definately different ways to do
solar.  I know for one you can do it with copper and buring one side.
Although any power you get from that specific proceedure will be a lot
lower than commercially available panels.

 For everyone that wants to take a look at what I'm describing.  This
PDF describes several different ways of making PV cells.  I'm referring
to the screen print method.

That pdf only describes how to make a copper-oxide PV cell and mentions
that screen printing is used to a) make contacts on crystalline cells
and b) make experimental lab PV cells. It doesn't mention how incredibly
inefficient copper-oxide cells are or how expensive and tricky screen
printing semiconductors can be. And no, I really doubt you can bake
your semiconductors in an ordinary BBQ.

Don't take my word on it though...
