Matlab code for I-V curve analysis of CIGS solar cells

The article presents the results of using one diode model for analysis a large number of the current-voltage (I-V) characteristics of solar cells (SC) with CuIn1-хGax(Se)2 (CIGS) absorption layer. Comparison of the model results with experimental curves showed the match of simulated and experimental IV curves with determination coefficients of more than 0.95. The developed model makes it possible to quickly process experimental data, i.e. I-V curves, and comparison of saturation current, ideality factor, proportional and series resistance, short circuit current, open circuit voltage, fill factor and efficiency from each curve before and after the experiments.
