More weird to me, after spending some time in the business, is all these solutions which only require "some engineering" are perpetually around the corner. People, stop taking "some engineering" or granted! :)

I would say that if I say "I have these solar cells that take sunlight and create electricity with 12% efficiency", I would expect that I get 12% of the total insolation in electricity. If I instead say "these solar cells take infrared sunlight and create electricity with 12% efficiency", then I expect it to be 12% of the infrared sunlight, not 12% of the total sunlight. It depends on what the hypothetical "fully efficient" case is.
