This article examines the best fraction of indium (x) and critical depth (H) of a single junction tandem photovoltaic (PV) cell (InxGa1-xN) in the vein to optimize its electrical efficiency. For better investigation, the optical and electronics…

The numerical simulation of the variation of the neutral molecule density induced by the strong correlation between the dynamics of the electron gas and that of the neutral gas is studied in a 2-D numerical modelisation. The energy injection is…

The authors express the Boussinesq equations of the laminar thermal and natural convection, in the case of permanent and bidimensional flow, in an annular space between two confocal elliptic cylinders. A new calculation code using the finite volumes…

In this work, we study numerically mixed convection flows in an open U-shaped channel. The right opening lets pass fresh air at cold temperature TC, while the walls of the channel are heated at the temperature TH > TC. Our study is based on a…

In order to gain an understanding of the mechanism of thermal performance increase in the shell side, a shell and tube heat exchanger is proposed in this study. Numerical investigations of the shell side fluid flow and heat transfer are performed…

In this work, a numerical study of a coupled transient heat and moisture transfer was realized. The program developed is simple compared with those developed by other researchers in the literature. We have exploited it, to compare the evolution of…

In this paper, the blow-up of solutions for a Dirichlet-Neumann problem to initial nonlinear viscoelastic plate equation with a lower order perturbation of p(x,t)-Laplacian operator in the presence of time delay is obtained. Under suitable conditions…

 In this paper, we construct the solution expressions of fourth order nonlinear difference systems

Φn+1       =                   Φn−2Ψn−3                       ,
        α + Ψn (±1 ± Γn−1Φn−2Ψn−3)
Ψn+1       =                  …

CuInSe2 thin films (CIS) are fabricated by flash evaporation in vaccum from a single source. Their optical properties are investigated by spectrophotometry in the range 0.3-2.5 . The interpretation of these results are based on the Mueller numerical…

Mircocrystalline silicon solar cells based on pin and nip layer sequences require an effective light trapping in the near infrared (NIR) to enhance the long wavelength spectral response. Therefore, the effect of interface roughness on the optical…
