The excess energy is converted to thermal (lattice vibrations), and ultimately coupled out through the surface to the surrounding medium.

Excitons Excitons are indeed an electron-hole pair, and the important feature here is that they are correlated. I.e., there is a significant Coulomb interaction energy, and they are bound such that to separate them, one must supply an energy equivalent to the "exciton binding energy".
