The climate change crisis and the running out of fossil resources are motivating the use of renewable energies. Solar energy is the main source of the renewable energies and photovoltaics is one of the main ways of photon conversion. This alternative energy is safe, clean and abundant. The purpose of this paper is the use of Maple software in: - Determining, without any approximation, the model physical parameters of real photovoltaic solar cell as a basic element of photovoltaic conversion. - Analyzing the effects of each physical parameter on real solar cell current-voltage characteristics and output power curve.

Photovoltaic energy is one of the most important renewable energies. This type of energy, unlike other energy sources, is clean, safe, and abundant. The photovoltaic solar energy is based on the conversion of sunlight into direct current by solar cells. In order to increase the efficiency of the photovoltaic conversion and for a better understanding of the solar cell behavior, an accurate knowledge of the cell physical parameters is required. In this work, the solar cell is considered as a generator and the one-diode equivalent circuit is retained. This electronic circuit modeling the solar cell contains a diode with its reverse saturation current and its ideality factor, parasitic series and shunt resistances and a photocurrent generator. In this paper, a new physical parameters extraction method is presented, for the first time to our knowledge, which is based on the current-voltage characteristics and on the analytical expression of the output voltage given in term of the Lambert W function. This method gives all the physical parameters without any approximation or introduction of initial values. To test the efficiency of the presented method, a comparative study with other extraction methods is done. The obtained results are in good agreement. [less ▲]
