“…Results and Discussions:-Density of excess minority carriers in thelamella: Figure (3) produces the profile of the carriers'densitywith the width of the lamella under short circuit. The minority carriers'maximum density increases under thermal agitation, in accordance with the Umklapp process [20,25,26,46,47]. The optimum thickness values are extracted from Figure 6 and are shown in Table 1 below.…”

Geometric parameters are an important data for the choice of solar cell architecture, for better conversion performance. As poor optoelectronic material is used, i.e. short minority carrier's diffusion length and under concentrated light which increases the temperature, it is then important to optimize the width of the lamella in order to have better photogenerated charge collection. Thus the intent of this work is the determination of the width of the lamella structure, presented through phenomelogical parametersmodeling study. These are the diffusion length and coefficient, as well as the surfacerecombination velocity of the photogenerated carriers in the base of the lamella silicon. The result gives a mathematical relationship between the optimum width and the operating temperature of the lamella solar cell, allowing to influence the industrial manufacturing process for the material economy.

In our work, we have been interested in conducting technological research on the use of photovoltaic energy for lighting. In fact, we have produced a stand-alone photovoltaic system with automatic search for the maximum power point, consisting of a photovoltaic module, a solar regulator, a storage battery and a digital control by microcontroller. The solar field is connected to the input of the regulator and the battery to its output. When the battery voltage is lower than the regulation voltage, the controller operates the photovoltaic generator at maximum power Pmpp and transfers this power to the output. In addition to the protection function, this regulator ensures tracking of the maximum power point (MPPT) and allows the photovoltaic generator to deliver its power whatever the variation of climatic conditions (sunshine and temperature). The main role of the solar regulator is the continuous monitoring of the state of charge of the battery to ensure its protection against overcharging and excessive discharging, the coupling and decoupling of the user as well as its maintenance. The principle of operation is based on controlling a DC-DC converter by a rectangular "PWM" signal generated by a PIC16F874 microcontroller which also controls the entire system. The results of simulation after realization were presented to illustrate the operation of the regulator by curves.

“…Authors have studied the electrical parameters of the solar cell namely the fill factor, the conversion efficiency, the power, the I-V and P-V characteristics under the Influence of Irradiation [1], from the back surface recombination velocity modeling in white biased [2], under temperature with the junction surface recombination concept [3], by acquisition automatic of I-V properties and temperature [4] [5], under influence of incidence angle on a vertical Silicon Solar [6], by illumination wavelength effect on a parallel vertical junction silicon solar cell and under irradiation [7] and illumination level effects on macroscopic parameters of a bifacial solar cell [8]. Our study is to determinate these electrical parameters from the optimal base thickness of the solar cell under variation of the irradiation energy flow and extracting the values of the recombination velocity at the junction, corresponding to the maximum power.…”
