Seasons greetings from La Paz, Mexico. ... They are thin foil and already damaged

across the joint... Not quite sure of how that would work in detail,
though...

Any ideas out there?

Thanks!

Solar panels are often made with soldered copper tape busses.
So copper tape and solder would be one way to go.
There is a siver loaded epoxy that can do reasonably well in thin
layers. It's expensive, naturally.

As for solder, one of the lead free formulations, 95 tin, 5 silver, is
twice as strong as the old 50/ 50 lead/tin and melts at 375. Some
have said there is a 25 year warranty, although how you can trust a
company to exist that long is beyond me
