研究目的
Investigating the effect of working pressure on the properties of RF sputtered SnS thin films and the photovoltaic performance of SnS-based solar cells.
研究成果
The study concludes that SnS thin films deposited at a working pressure of 2.0 Pa exhibit the highest power conversion efficiency of 0.58% in SnS-based solar cells, attributed to optimal structural and optical properties.
研究不足
The study is limited to the effects of working pressure on SnS thin films and solar cells, and does not explore other process parameters or alternative materials.
1：Experimental Design and Method Selection:
SnS thin films were deposited by RF magnetron sputtering at varying working pressures (
2：6 Pa to 6 Pa). Sample Selection and Data Sources:
SnS thin films were formed on SLG and Mo-coated soda-lime glass substrates.
3：List of Experimental Equipment and Materials:
RF magnetron sputtering system, SnS target, SLG and Mo-coated substrates.
4：Experimental Procedures and Operational Workflow:
Substrates were cleaned, mounted in a vacuum chamber, and SnS thin films were deposited under varying pressures.
5：Data Analysis Methods:
XRD, XPS, Raman spectroscopy, FE-SEM, UV-Vis-NIR spectrophotometry, and solar simulator for J-V characteristics.
