In recent years, Gallium Antimonide (GaSb), which has smallest bandgap among III-V semiconductors family, became the subject of extensive investigations in the field of thermophotovoltaic (TPV) converters, because of the recent improvements in…

L’alimentation en eau potable et d’irrigation reste toujours le souci quotidien des populations des régions enclavées et sahariennes. Le pompage de l’eau à l’aide de l’énergie solaire photovoltaïque est une solution bien adaptée pour ces régions. En…

Compte tenu de l’épuisement des énergies utilisées actuellement, telles que les énergies fossiles, et du constat établi par les experts concernant les exigences écologiques, il est nécessaire de trouver des nouvelles sources d’énergies afin de…

Dans cette étude, nous présentons les résultats expérimentaux relatifs aux expériences menées sur des capteurs solaires plans à air. En premier lieu, nous décrivons les différentes configurations étudiées. De ce fait, nous avons opté à combiner trois…

In this paper, we will study the maximum number of limit cycles of a perturbed differential system with respect to its parameters which appear in the system specially on the degree of the polynomials. For this we will use two methods namely the…

The Doped Oxide Solid Source (DOSS) diffusion technique is well suited for fine-tuning of the surface concentration. The dopant surface concentration is important during phosphorus emitter diffusion due to the opposite requirements of a lowly doped…

In this work, the excitons distribution function in organic bulk heterojunction solar cells, at a depth z has been determined from solving the charge continuity equation, by exploiting the Laplace transform with an appropriate boundary conditions.…

In this paper, the results of investigation of the spectral characteristics of the injectional photodiodes with a varied base are presented under the condition of the existence of Galvanomagnetorecombination (GMR) effect. This is the redistribution…

With the decline in price of the photovoltaic’s (PVs) and the increase in greenhouse gases due to the use of fossil fuels the use of photovoltaic as a power source for water pumping is becoming the more attractive solution instead of using…

The convergent-divergent nozzles have many industrial uses such as wind turbine, the blades of turbine engines, aircraft wings and screw propeller. The main objective of this study is to identify and evaluate the physical properties of the…
