In this work, a maxi dual axis solar tracker is proposed. This tracker is used to track the sun path within a day and during a year. The tracking system is composed of two parts: mechanical and electrical parts. The mechanical part is composed of…

In this work we present the results of the numerical simulation study of the electrical characteristics of a CIGS-based thin film and heterojunction solar cell and their interpretations. First, we will simulate two solar cells of structures:…

In this study, we analyzed Zinc Oxide (ZnO) thin films deposited on silicon substrates using magnetron sputtering. These films have numerous applications in photovoltaic and optoelectronic devices due to their excellent physique properties. We used…

An optimization method is proposed and applied to study a PV-electrolyzer system consisting of Solarex MSX60 modules and PEM electrolyser H-Tec StaXX7 stacks. A total of 41 series-parallel combinations of PV modules and electrolyser stacks were…

Ce travail consiste à étudier la simulation numérique de la convection naturelle bidimensionnelle laminaire et permanente dans une cavité carrée différentiellement chauffée remplie d’air. Les parois verticales soumises à des températures constantes,…

Dans une certaine plage de nombre de Mach, l'interaction entre une onde de choc oblique et une couche limite s'effectue par une investigation numérique sur une plaque plane athermane, basée sur la résolution des équations de Navier-Stokes…

The objective of this study was to evaluate in vitro the antioxidant activity of polyphenols from olive oil mill wastewater in Khenchela region eastern of Algeria after conducting a phytochemical screening. The extraction of polyphenols was done by…

The aim of this paper is to present a graphical user interface developed under Labview environment that allows, from experimental data, the calculation and extraction of parameters of the one diode model and of the parameters in reverse bias and all…
