• Current-voltage characteristics
• Parameters extraction
• Lambert W function
• Polynomial curve fitting

A new method is proposed to describe the characteristics of solar cell and module in this article. By using the exact explicit analytical solutions, the current-voltage and power-voltage curves of the corresponding modules are calculated and simulated. In order to extract the parameters of the solar cells, an optimized technique is presented by using Lambert W function and polynomial curve fitting. The accuracy of the model is compared with previous methods in other work. Results have the good agreement between the fitted current-voltage curves and the experimental data. Moreover, error and statistical analyses are carried out to illustrate the accuracy of the estimated parameters and procedure suitability.
