Depends on how long a view you take.  If your horizon of interest is the few
scores of years we get before we die, then no, not much hope of seeing PV
outside of niche applications.  But it seems reasonable to expect
incremental improvements in efficiency.

Looking at centuries or eons, who knows?  After the oil is gone and we can't
find any more nuclear fuels, then maybe parking a few million hectares of PV
into solar orbit will make financial sense.  But I'd bet money on deep
geothermal before orbital PV.

Obviously not, but it may be approached asymptotically.  Knowing that you
cannot get there does not make it pointless to try getting closer.

Based on past performance, I really do expect science and engineering to
present us with incremental improvements in all areas.  Unlike those who
seem to be conceited enough to believe that we've already learned everything
and done everything, I will only be surprised if there ISN'T progress.

You read too many newspapers written by clowns who shouldn't be in charge of as
much
as a pencil.

We're in the process now of just refining things. The major breakthroughs were
made
LONG ago.
