Modélisation d’une cellule solaire à puits quantique en GaAs/AlGaAs

Abstract

The greatest challenge of the researchers being interested in the renewable environment and energies is to carry out a good output /price on the solar generators in particular in die statement With regard to the third generation of solar cells, the quantum solar cells represent the response to many interrogations. The work of our thesis related to modeling of a solar cell with heterojunction, with quantum well containing the arsenic of galium GaAs to notched joints of the AlGaAs window. The goal and to determine characteristic I (V) of the cell, the influence of the parameters physical and geometrical on the output of conversion especially the density of the electrons in the quantum well and to profit from electronics qualities and physics as of these two materials, a current of short circuit, a tension of open circuit and a close absorption will infra it red better.
