Abstract
In this work, the heterojunction composed of a n-type ZnO transparent conductive oxide (OTC) layer, a n-type CdS buffer layer and a absorber layer based Cu (In, Ga)Se2 p doped is studied under the influence of a KF layer placed in the CIGS/CdS interface. This study was done by varying the thickness of KF using thin-film simulation software named SCAPS-1D. The presence of KF for a doping of the CIGS absorber of 1016cm-3 improves strongly the electrical parameters that are the Vco, the Jcc the FF, the maximum power and the conversion efficiency of the solar cell Ƞ. However, a decrease of the FF and the Jcc is noticed when the thickness of the KF is greater than 30nm causing a deterioration of the performances of the cell.
Highlights
During the past three decades, CIGS-based solar cells have been widely studied and significant progresses have been realized leading to an increasing development of this technology
A numerical simulation study of the influence of the thickness of the potassium fluoride layer is made on the macroscopic electrical parameters of the solar cell
The parameters characteristic of the cells which are usually used in to describe the performance of the cell more are open-circuit voltage (Vco), the density of short-circuit current (Jcc) and the factor of form (FF)
Summary
During the past three decades, CIGS-based solar cells have been widely studied and significant progresses have been realized leading to an increasing development of this technology. Various record yields have been reported in the literature in recent years: EMPA: 20.4 %( Chirilă, A. and al., 2013), ZSW: 20.8% (Jackson, P. and al., 2014), Solar Frontier: 20.9% (Kushia, K., 2014), Solibro 21.0% (Herrmann, D. et al, 2014), 21.7% (Jackson, P. and al., 2015) and 22.7% (Jackson, P. and al., 2016). The use of potassium fluoride allowed the optimization of the efficiency of the solar cell. Studies on the beneficial effect of potassium fluoride on the generation and recombination of carriers in this type of cell have already been published (Niane, D. and al., & Niane, D. and al., 2018). A numerical simulation study of the influence of the thickness of the potassium fluoride layer is made on the macroscopic electrical parameters of the solar cell
