SolarCellEff:

------------------------------------------------------------------------
   Solar cell monchromatic efficiency.
   This is the efficiency when exposed to monochromatic light in the
   bandgap. At 0 deg-K the efficiency will be 1.
------------------------------------------------------------------------
   Form:
         SolarCellEff
   eff = SolarCellEff( T, s )
------------------------------------------------------------------------

   ------
   Inputs
   ------
   T          (1,:) Temperature (deg-K)
   s          (1,:) Either 'silicon' or 'gallium arsenide'

   -------
   Outputs
   -------
   eff        (1,n) Monochromatic efficiency
