EVA

I've been looking everywhere, and I just cant track it down. I did find some epoxy that  is apprently made specificly for encapsulating solar cells, but its something like $250 per gallon, so it just really wouldnt make any sense.

If you type the full name into googles search bar there are pages and pages of info.

Yeah, but the problem isnt finding info on eva, its that unfortunately none of the info points to a retail supplier.

Looking at one of the google links http://www.indianplasticportal.com/eva.html it says that it's opaque and the melting point is 176 degrees F. Are you sure you want to use this on a solar panel?

Well, they're used somewhere in a solar panel. Evergreen's site says of their solar panels:

"Industry standard EVA (Ethyl Vinyl Acetate) and Tedlar construction protects solar cells from mechanical and environmental stress."

I'd love to be able to dissect a real, professional solar panel. I've never even seen one in real life though, only in pictures.

Old Solarex's had tempered glass on the front,

the kind that breaks into tiny pieces.

It was sealed at the edges, but not to the cells.

The cells were fastened to another layer, possibily of glass.

Tedlar is like sticky plastic tape on the back.

I wish I had not learned that.
