Good thermodynamics treatment right there. However, the whole point is
that the Carnot cycle /does not apply/ because the processes are
simply not the same.

I did suggest roughly how a solar cell could be incorporated into a
heat engine to show that it has the same efficiency bounds.  The OP's
Q was close enough to field.  Obviously a photovoltaic cell is not the
same as a gas working between T_hot and T_cold -- anybody can see that
much!

-----------------
anyway
my intuition tells me that the Carnot law (btw how do yop
spell Carno in french ?)
so
i think that somehow that law can be **expanded*
to the electricity world and the
thermo/photoo electric fields

if it is really as i hear-ed the new patents of solar cells
can be promoted to 60 percent efficiency -
it is a huge revolutionary good news 9
for r world energy crisis ....
