Contribution to the evaluation of the illuminated solar cells parameters

Abstract

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.

Photovoltaic Cell Parameters Identification Using Nonlinear Mathematical Programming

“…A Simulated annealing based approach is proposed in [5] for optimal estimation of solar cell model parameters. In [6], [12] numerical curve fitting procedures are used to estimate the cell model parameter: a non-linear two-point interval division and particle swarm optimization algorithm were then applied to extract local parameters from the current-voltage data at search measurement point. An extraction method that avoids the measurements of the peak power point and I-V curve slope which is based on the power law I-V model is proposed in [7].…”
