Abstract

We review the thermodynamic limit of multiple exaction generation (MEG) solar cells from single junction to multijunction approaches. Introducing limit of open circuit voltage (Voc) shows near identical results between (1) multiple carrier recombination (MR) and (2) single carrier recombination (SR). After applying this concept into multijunction with MEG (MJMEG), we have found similar results between MR and SR with limited VOC due to optimum chemical potentials between two cases. Therefore. SR case with limited VOC can be available to use the recombination current for MEGSC and MJMEG devices under the certain condition.
