Jeff,

I don't think these discussions are OT at all; please don't hold back the
technical information.  This is good stuff.  Thanks for sharing your
expertise.

If the sensors are inefficient, capturing less than 100% of the photons,
wouldn't increasing sensor efficiency be the same as enlarging a cell of the
same efficiency? 

How efficient are our sensors?  Occasionally I see articles on solar cells,
and the efficiency of them seems to be slowly getting better, but progress
seems agonizingly slow.
