Exceeding the Shockley-Queisser Limit: Multiple Exciton Generation (MEG)
Nanocrystal-based solar cell efficiency can be theoretically improved by the generation of multiple electron-hole pairs from the absorption of one photon.
MEG been demonstrated in nanocrystals (quantum dots) such as PbS, PbSe, PbTe, CdS, CdSe, and InAs, as well as in single-walled carbon nanotubes.
The origin of MEG is complicated and still under debate, but one explanation is that light excites a high energy exciton which then decays irreversibly into a quasi-continuum of states available at that energy.
