A 3X improvement is not an order of magnitude, which would be 10X.
Agreed. In the 10x case, I'm talking about energy density per unit of
area, of the detector itself. In the 3x case, I'm talking about the
solar collector assembly as a whole. The discrepancy is due to gathering
a large area of light and focusing it on a small detector.
Detector? What is a detector?
Maybe I'm using a non-standard term. Solar cell?
