Has anyone tried making solarcells with the silkscreening process?

I read about and saw a couple of news reports about a process to make solarcells by silkscreening. I saw a couple of posting around the web stating that there is information on how to do it cheaply at home.

Does anyone know where to find the info?
Has anyone made any yourself?
Does anyone know the materials used?

Thanks

I've seen the silk screening articles, I severely doubt that doing that at home would be practical, it would still require a full clean room environment and very expensive materials and toxic and hazardous chemicals, which should NOT be in the general populations hands.
