Abstract:
In the work, tandem solar cells were designed to achieve improved efficiency using Sb2Se3/Si as the materials. The work involved simulating the Sb2Se3/Si structures, where Sb2Se3 served as the top cell and Si as the bottom cell, under AM1.5 G solar spectrum illumination using the one-dimensional device simulator Scaps. The obtained results demonstrated a significant increase in the efficiency of the Sb2Se3/Si tandem solar cell. Initially, the top cell had an efficiency of 14.29%, while the bottom cell had an efficiency of 11.22% when considered as single cells in a row. When used in tandem, the efficiency of the Sb2S3/Si tandem cell improved to 14.6%. Additionally, there were notable improvements in the electrical parameters of the solar cell. The overall efficiency (ƞ) reached 21.41%, the open-circuit voltage (Voc) was 1.37volts, the short-circuit current density (Jsc) was 19.78 mA/cm2, and the fill factor (FF) reached 78.62%. These results highlight the success of the Sb2S3/Si tandem solar cell in achieving higher efficiency and improved electrical performance compared to single cells.
