Solar cells from the 70s are still something like 70-80% of their original efficiency. They die slowwwwly. Far more likely in such time is we'll find better materials that are much more efficient to replace them with. 20% conversion today is pretty low. If we could get that up to 30 or 40%, that would enable solar even in cloudy climates.
