Résumé:
photovoltaic cells are components capable of directly converting light
energy into electrical energy, with the help of certain semiconductor materials. In this
work, we have studied and simulated the characteristics of a CZTS-based cell using
COMSOL software. Simulation results showed that cell parameters such as the
thickness and gap of the absorbing layer play an important role in cell performance.
An optimal conversion efficiency of 26% was obtained for a thickness of the
absorbent layer of the order of 1.5 μm and a gap of 1.4-1.5eV.
