Sorry r8rchris I skimmed that report too quickly the first time.Triffid

Ok here I go:The patent#5,538,903 is on screen printing solar cells onto glass.The pdf article that r8rchris so generously supplied  on page 1 tells you that you can screen print on aluminum foil in these manner:
5)metal ink(screen pattern)(neg electrode)
4)(n-type)mixed cadium sulphide and cadium chloride and proylene glycol.
    also known as the (CdS layer).
3)(p-type) an equi-mol  mixture of cadium(Cd) and tellurium(Te) powders with addition of CdCl2 and PG(proylene glycol).
2) carbon electrode layer with silver and indium mixed in.
1)aluminum foil (pos electrode)
I hope someone here makes these and posts their results.

Whoever makes these here should read the pdf article and the patent r8rchris supplied for construction tips and sources for the chemicals.Also a propane outdoor grill is suggested to do the baking.The patent talks about using 600 degrees C. to bake with.Also mixing details are there plus concern about using vibration to reduce the bubbles in the pastes.When I first heard of this method it was about 10 years ago and some guy in kansas
used his kitchen oven at its max temp for like an hour.The landlord was concerned he was going to burn the apartment down and ordered him to stop.It was said in the article that his solar cells were working.Triffid

I am very interested in this, if someone can try it out and then give an easier step by step instruction guide, that would be great.  600 C is very hot!
