Optimisation de l’efficacité des cellules solaires à base de CuInSe2, modélisation et simulation.

Abstract

In a global context of diversification of the use of natural resources, recourse to renewable energies and in particular solar photovoltaic is made more and more. As such, the development of a new generation of CuInSe2-based photovoltaic cells seems promising. This thesis focuses on CuInS2, which belongs to the family of ternary compounds in the chalcopyrite form. In the photovoltaic field, the most recent studies have been mostly devoted to thin films, due to their great prospects in the sector of photovoltaic modules with large surfaces. Its crystalline structure, its optical and electrical properties as well as the intrinsic and extrinsic defects encountered in this material make it a promising material for scientific research. SCAPS-1D software was used in this study to model a CIS-based solar cell while optimizing its electrical characteristics, in particular the efficiency of the solar device.
