  Multiple exciton generation solar cells (MEGSCs) undergo low efficiency due
to material imperfections such as nonradiative recombination This paper
introduces alternative approaches for realizing photovoltaic (PV) devices
similar to MEGSCs. Furthermore, we reorganize the detailed balance equation of
MEGSCs such that it is similar to that of independent connection tandem solar
cells. This is possible because of the spectral dependence of the ideal QY.
Finally, we compare these two similar equations and propose alternative
approaches for realizing MEGSC-like tandem solar cells. We explain the
difficulty in fabricating MEGSCs, which arises from the high rate of
non-idealities. In this regard, the deconstruction of the detailed balance
equation of MEGSCs can reveal alternative paths for replacing MEGSCs with
tandem solar cell configurations.
