In this study, we present the study of the photo-thermal response of a monofacial silicon solar cell illuminated by a multispectral light for a constant modulated frequency. Solving the continuity equation for minority carriers in the base of the solar cell resulting in the terms of the heat equations in the presence of an optical source. The density of minority carriers in excess, the amplitude of the variation of temperature and the heat flux density were studied and analyzed for different angular pulses and rates of recombination at the junction. Representations of Nyquist and Bode plots of the thermal dynamic impedance resulted in an equivalent electrical circuit of the photocell. © Maxwell Scientific Organization, 2013. Source

Such as millet, corn and transformed into "couscous", "arraw" or "thiakri" that fit for human consumption. They are widely used in Senegal where about 70% of the population feed on these products because of their nutritional value and also their availability. Today, only in the small industrial zone of Thies, one can count four producers, who produce each: few tons. But the major problems they face are the drying and packaging of these products after their transformation process. This article is based on the drying of rolled products. It reveals that the granulometry is an extremely important factor in the drying process. The testing on the rolled products showed that the small ball does not dry out faster than larger, as is often thought. This assertion is not always true. This study allowed us to show the different scenarios that may arise as well as their limits. In addition, we determined that the equation of the drying curve of rolled products is generally in the form polynomial of level 4. © Maxwell Scientific Organization, 2012. Source

We present in this study the determination of the equivalent electrical circuits associated to the recombination velocities for a bifacial silicon solar cell under frequency modulation and monochromatic illumination. This determination is based on Bode and Nyquist diagrams that is the variations of the phase and the module of the back surface and intrinsic junction recombination velocities. Their dependence on illumination wavelength is also shown. © Maxwell Scientific Organization, 2012. Source
