Conception et étude numérique de cellules solaires à double absorbeur à base de tellurure de cadmium (CdTe) et de disiliciure de fer (FeSi2)

Abstract

FTO-based inorganic solar cells with dual CdTe and FeSi2 absorbers have recently attracted a lot of attention because they offer superior thermal stability and good optoelectronic properties compared to conventional solar cells. In order to increase the efficiency (η), and improve the performances of the Cu/FTO/In2S3/CdTe/FeSi2/Ni cell), the SCAPS-1D software is used as a tool for optimization and analysis of the electrical parameters (PV) of this cell. We first evaluate the short-circuit current Isc, the open-circuit voltage VCO, the form factor FF and the electrical efficiency η of the cell, then we are interested in the effect of the thickness and the doping concentration of each layer on these parameters.
