N2 - A semi-analytical model is established by extending the detailed balance models to explicitly elucidate the impact of nonradiative recombination and other aspects of actual devices, including photon recycling, spontaneous emission coupling, and non-ideal absorptance and emittance. Through which many important practical design parameters for concentrated photovoltaic multijunction solar cells are taken into account, such as bandgap energy, junction number, solar concentration, and material quality expressed as Shockley-Read-Hall recombination saturation current density. The model can accurately predict subcell layer thicknesses and bandgaps as function of material quality. Novel characterization techniques for multijunction solar cells are also established to measure the external quantum efficiency and to explain the commonly encountered artifacts under practical test conditions.
