Summary:In this work, we present three new Mathematica [1] codes written to extract physical parameters of illuminated solar cell from its current-voltage characteristic. The solar cell is modelled by a circuit containing a p-n junction photocurrent I ph , a reverse saturation current I s , an ideality factor n, a shunt resistance R SH and a series resistance R S . The three codes are based on the following methods: the five points method [2], the Ortiz-conde method [3] and a new method developed in our laboratory, where we determine experimentally the value of series resistance R S , define a new variable x = V - R S I and fit numerically the expression of the current I as a function of x to the simulated data.
