Current-voltage (-) curves from the 1-diode/2-resistor (A-1 and A-2 methods) and 2-diode/2-resistor equivalent circuit models to the Emcore ZTJ triple-junction (InGaP/InGaAs/Ge) solar cell (left). The experimental data corresponding to this cell, measured at AM0 (135.3 mW/cm²) and 28°C, has been also included in the graph. Differences between the currents from the studied models and the testing data are included in the right graph.
