I don't know what point you're trying to make here. The efficiency with regard to what?
Joules out per unit of currency in? Joules of electricity out per joules of sunlight in? PV is great at those even in the dark moist British Isles, which are about as bad as southern Alaska.
Nuclear however, is really expensive. Situationally useful, but really expensive — So expensive in fact that it's about the same as using dedicated batteries (rather than hydroelectric or hydrogen or refurbished batteries) to support PV when it's too dark.
