Abstract
In this paper, an initial model based on a CIGS experimental device has been established. Afterwards, the conventional i-ZnO layer replaced by ZnO1-xSx or Zn1-yMgyO layers as window layer and the solar cell performance analyzed. The estimated optical bandgap (Eg) of Zn1-yMgyO material is linearly enhanced from 3.3â¯eV for pure ZnO to 4.1â¯eV for Zn0.6Mg0.4O. Also, Eg for ZnO1-xSx material is variable between 2.83â¯eV-3.76â¯eV that is wider than pure ZnO. The AlZnO/ZnO1-xSx/CdS/CIGS structure when 0.4â¯<â¯xâ¯<â¯0.6 and the AlZnO/Zn1-yMgyO/CdS/CIGS structure when 0.055â¯<â¯yâ¯<â¯0.2 are the proposed solar cells with 21.15% efficiency.
