Abstract: The Simpson order 5 integration method has been implemented in an executable program, to extract the five solar cell parameters, within the one-diode solar cell model. This integration method is used to integrate the Current minus the Short-Circuit Current, yielding a more accurate Co-Content function than the using the trapezoidal integration method. The program then fits the Co-Content function to a second-degree polynomial in two variables, namely, the Voltage and the Current minus the Short-Circuit Current, yielding six fitting constants, and the five solar cells are extracted from them. The program also calculates the standard deviations of the fitting constants, and from the, the standard deviations of the five solar cell parameters are also extracted. The results are given to the user in three text files, from where the user can easily access them or export them to other softwares. A video is also given, explaining how to use the executable program. The executable program provides the results in four seconds or less, in striking contrast with the tenths of minutes required by other methods, as they have to be implemented manually.
