This paper summarizes our activities in the field of process technologies for the fabrication of photovoltaic devices. The study is strongly focused on the integral screen printing technique for the fabrication of single crystal solar cells, using…

In speed control, double-fed-induction generator (DFIG) has attracted attention in wind energy conversion systems (WECs). These systems can offer higher performances by controlling converters that connect the generator windings to the grid network.…

This paper proposes a control method for the maximum power point tracking (MPPT) of a photovoltaic system and this with the aim of increasing the output power of a photovoltaic system. An electronic controller is built-in between the photovoltaic…

In this study, numerical simulations are performed to investigate the effect of the position and jet angle of the synthetic jet on the aerodynamic characteristics of a wind turbine blade profile. The study is applied to the NREL S809 profile with a…

Nous présentons, dans cet article, des relations simples de forme polynomiale pour déterminer les propriétés thermodynamiques du fluide frigorigène R134a par simulation sans avoir recours aux abaques. Les relations proposées ont été déterminées par…

Research and development of affordable, sustainable, and low-carbon energy sources capable of reducing dependence on fossil fuels, contributing to social and economic development, and improving environmental and health skills have become a global…

On se propose d’étudier et de caractériser expérimentalement l’effet d’une perturbation sur le profil de la couche limite se développant le long d’une plaque mince. Cette perturbation a été provoquée par la présence d’un papier de verre placé sur le…

L’objectif de ce travail est de vérifier l’application des modèles permettant de reconstituer les moyennes mensuelles par jour des irradiations globales et diffuses sur un plan horizontal. Les modèles choisis ont été proposés dans la littérature par…

In this paper we are interested in developing new and easy software for the sizing of a solar installation of hot water production. Such installation is successful only if its determination, its conception and its realization are made with care. This…

In this paper, we report on the simulation of steady state photoconductivity in un-doped a- Si:H at temperatures from 30 to 500 K. The model is based on recombination at dangling bond states and band tail states. It takes also into account the…
