Complex sentence: Note that in the event of multiple exciton generation (MEG), quantum efficiencies of greater than 100% may be achieved since the incident photons have more than twice the band gap energy and can create two or more electron-hole pairs per incident photon.
Split into simpler sentences: Note that in the event of multiple exciton generation (MEG), quantum efficiencies of greater than 100% may be achieved. This is because with MEG the incident photons have more than twice the band gap energy and can create two or more electron-hole pairs per incident photon.
