I don’t think you can just add up efficiency percentages like that…

Sure you can. That's why a UV lamp shining at the six 20% solar panels that power it can run your FTL drive.

Just need another sun on the opposite side

I think you're right there. My bad.

They say the second layer retains 93% of the performance of the first using reflected light, making it 20% efficient, so, yes they are added in that case.

You double(ish) the surface area. So 23% efficient front panel + 20% rear panel.
