It only stops half the light. I think the thermal windows on our Nevada house stop about 2/3 and they don't noticeably hamper visibility at night. (Half the energy is about 3db, which is barely detectable in the logarithmic response of the eye.)

Indeed, I can understand that. And it's a nice idea.

But the implication is still that I'd have to get specially-constructed double-glazed doors, yes, which would be fiendishly expensive I'll bet!

They're fiendishly expensive WITHOUT the solar panel - just with low-E glass and a frame. If the low-E coating could be made as a solar panel without a price change you'd get the power for the cost of the extra wiring. If not, you get it for that plus the price difference (presuming you were going to install low-E windows anyhow).

That delta might be far less than the cost of a full-blown panel assembly - glass, frames, wiring, mounting, ...

OK, indeed.

Well, if we have to have some custom-made double glazing done, and it is entirely possible that some of our 40-year-old falling-apart stuff is going to need repair or replacement, then I'll see if we can put in (say) some of Schott's laminate stuff in the outer pane.
