Default Solar absorption lines

But if I look at solar spectra, I don't see any significant
emission lines convolved with the continuum.


The emission lines are there. The continuous spectrum is produced by
the photosphere and the lines are produced by the chromosphere. When
there is an eclipse of the sun a spectroscope aimed at the limb of the
sun will show a flash spectrum of emission lines in that brief period
of time when the moon hides the photosphere but exposes the
chromosphere. The emission lines are at the same wavelengths as the
absorption lines.
