In this work, we study the method for determining the maximum of the minority carrier recombination velocity at the junction Sf max , corresponding to the maximum power delivered by the photovoltaic generator. For this, we study the temperature influence on the behavior of the front white biased solar cell in steady state. By solving the continuity equation of excess minority carrier in the base, we have established the expressions of the photocurrent density, the recombination velocity on the back side of the base Sb, and the photovoltage. The photocurrent density and the photovoltage are plotted as a function of Sf, called, minority carrier recombination velocity at the junction surface, for different temperature values. The illuminated I-V characteristic curves of the solar cell are then derived. To better characterize the solar cell, we study the electrical power delivered by the base of the solar cell to the external charge circuit as either junction surface recombination velocity or photovoltage dependent. From the output power versus junction surface recombination velocity Sf, we have deduced an eigenvalue equation depending on junction recombination velocity. This equation allows to obtain the maximum junction recombination velocity Sf max corresponding to the maximum power delivered by the photovoltaic generator, throughout simulink model. Finally, we deduce the conversion efficiency of the solar cell.

a r t i c l e i n f o Keywords: Photovoltaic (PV) Modeling Maximum power point Maximum power point tracking (MPPT) a b s t r a c tIn this work, we present a generic model based on universal of mathematical equations to model the operation of a solar cell. We analyze the output current and the electric power supplied by a solar cell according to the output voltage, temperature and power. The results obtained show that the model is very effective in treating the simulation model of a solar cell on the one hand and secondly the ability to model in an efficient manner a photovoltaic field with fewer errors. This allows operating the photovoltaic generators in optimal conditions, and consequently with a better exploitation of energy.

“…In these studies [72,84,85], the photocurrent and the diode saturation current are changed with irradiation and temperature, respectively, and the other parameters are determined by taking a reference operating condition. New methods [78,86,87] are also presented in order to compute the different parameters of interest such as parasitic resistance or conductance (since the mathematical calculation of the reciprocal value of the shunt resistance is equivalent to a conductance). Under a stable environment with little performance requirements, these methods can be a good choice.…”

Mobile electronic devices such as MP3, mobile phones, and wearable or implanted medical devices have already or will soon become a necessity in peoples' lives. However, the further development of these devices is restricted not only by the inconvenient charging process of the power module, but also by the soaring prices of fossil fuel and its downstream chain of electricity manipulation. In view of the huge amount of solar energy fueling the world biochemically and thermally, a carry-on electricity harvester embedded in portable devices is emerging as a most noteworthy research area and engineering practice for a cost efficient solution. Such a parasitic problem is intrinsic in the next generation portable devices. This paper is dedicated to presenting an overview of the photovoltaic strategy in the chain as a reference for researchers and practitioners committed to solving the problem.
