ABSTRACT

The photovoltaic performance (efficiency η) of an ITO/CdS/CdTe structure cell is studied in this article according to its electrical properties. The study is carried out by simulation with SCAPS (Solar Cell Capacitance Simulator) whose mathematical model is based on solving the equations of Poisson and continuity of electrons and holes. An electrical conversion efficiency of 23.58% is obtained by optimizing the mobility of the electrons (100 cm²/Vs), that of the holes (25 cm²/Vs), the density of electrons (10¹⁵ cm^-3), the density of the effective states in the conduction band (7.9 × 10¹⁷ cm^-³) and the electronic affinity (3.85 eV) of the CdTe absorbent layer.
