Energy conversion efficiencies for solar cells utilising multiple carrier excitation were calculated for various solar concentration factors based on the detailed balance limit formalism. The theoretical efficiency limit for the solar cells generating up to eight electron-hole pairs from one photon was 58% under a 1000-sun illumination relative to 38% without multiple carrier excitation with their optimised energy bandgaps.
