    ABSTRACT: The necessity to find new forms of renewable energy is very important and urgent nowadays. The renewable sources of energy derived from the sun are one of the promising options. The photovoltaic cells as one of renewable energy sources have been largely studied in order to obtain cheap, efficient and secure PV cells. The conversion efficiency is the most important property in the PV domain. Indium gallium nitride (InGaN) alloys offer great potential for high-efficiency photovoltaics. We present numerical simulations of GaN/InGaN heterojunction solar cells by SCAPs simulation. The calculation of characteristic parameters: short-circuit current density, open-circuit voltage, and conversion efficiency. So, these simulations study the effect of indium content and thickness in these parameters. While the maximum efficiency of a p-n GaN/InGaN heterojunction solar cell with 0.2 indium composition is 2.78%, above an indium composition of 20%, the modeled heterojunction devices do not operate as solar cells.

    ABSTRACT: Batch digestion experiments were conducted to determine the effects of inoculums/substrate ratio of three different ratios (ISRs) 0.3, 0.5 and 1. The substrate chosen in this study was slaughterhouse waste from Adrar city (south west of Algeria). The inoculation was made by sludge issued from wastewater treatment plant. During this study, several parameters of anaerobic digestion were measured, such as pH, VFA, AT and volume of the produced biogas. pH variation and VFA/TA values have shown high stability of anaerobic digestion process.

    ABSTRACT: At the dawn of the twenty-first century, one of the major problems of mankind is to combine the energy, the respect for environment. A problem of sustainable development has been clearly demonstrated in the Earth Summit in RIO (2012). Among the major battles to be fought in this century for the survival of the planet is to include energy efficiency as an international political priority, reduce emissions of greenhouse gases. Renewable energy, inexhaustible, clean, are needed in these conditions as a priority.
