“…Practical applications of solar cells require simple lumped models and efficient parameter extraction methods. Parameter extraction in solar cells has been a research topic for many years [1] and several articles [2]- [11] have reviewed over time the different parameter extraction methods in diodes and solar cells. Although last year Cotfas et al reviewed [2] 34 different methods, not all the methods were included.…”

This article presents an up-to-date review of several methods used for extraction of diode and solar cell model parameters. In order to facilitate the choice of the most appropriate method for the given particular application, the methods are classified according to their lumped parameter equivalent circuit model: singleexponential, double-exponential, multiple-exponential, with and without series and parallel resistances. In general, methods based on numerical integration or optimization are recommended to reduce the possible uncertainties arising from measurement noise.

The series resistance (Rs) of a solar cell is commonly represented as a constant resistance value. However, because of the distributed nature of series resistance, the effective lumped Rs vary with current density and illumination intensity. Treating Rs as a constant is usually insufficient for an accurate analysis of its J–V curve. This work first presents a review of the distributed nature of series resistance and commonly applied methods to measure Rs. Particular attention is given to the multi‐light method (MLM) and it is discussed in detail, where Rs in both the light and dark can be measured as a function of current by extracting Rs from a set of current–voltage (J–V) curves attained at different illumination intensities. The principle behind this method is discussed, and the results are then compared with those of other known methods of Rs measurement. The accurate measurement of Rs(J) attained with the MLM permits the extraction of an Rs‐corrected J–V curve, which is theoretically more accurate than that attained by alternative methods because of negligible error from injection dependence and spectral mismatch. With the solar cell equation modified to include Rs(J), we attain a much better fit to experimental data, finding a significant reduction in error compared with using a constant Rs.

“…Extracting these parameters is of vital importance for quality control and evaluation of the performance of solar cells when elaborated and during their normal use on site under different conditions of temperature and illumination. Recent published works [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] have been proposed by several authors to determine the values of Rs, n, Is, I ph , and Gsh. Some use the illuminated and dark I-V conditions [1,2], while others use dynamic measurements [3,4] or integration procedures [5] based on computation of the area under the current-voltage curves.…”

A contribution to the evaluation of the illuminated solar cells parameters (the series resistance Rs, the ideality factor n, the saturation current Is, the photocurrent Iph, and the shunt conductance Gsh) is dealt with in this paper. The suggested method uses the illuminated current-voltage (I-V) characteristics and the voltage dependent differential slope curve δ of solar cells. The procedure is verified using simulated and experimental I-V curves of different solar cells and modules. The extracted values are in good agreement when compared to the calculated values obtained by other published methods.
