A one-dimensional theory of high base resistivity tandem-junction solar cells in low injection

A one-dimensional theoretical model of the Tandem-Junction Solar Cell (TJC) with high base resistivity and under low-level injection is derived. The model provides a theoretical basis for a previously published conceptual model and allows for the calculation of the spectral response and other performance parameters, namely, Isc, Voc, Pm,FF, and η, under variation of one or more of the geometrical and material parameters and 1-MeV electron fluence. Sample calculation results of computer simulation of this model are presented.
