研究目的
Investigating the effects of strontium doping on the structural, optical, and electrical properties of cuprous oxide thin films for solar cell applications.
研究成果
Strontium doping improves the structural, optical, and electrical properties of Cu2O thin films, making them suitable for solar cell applications. The best performance was observed at 7% Sr doping, with a solar cell efficiency of 0.75%.
研究不足
The study is limited to the effects of strontium doping up to 7% on Cu2O thin films. The solar cell efficiency achieved is relatively low (0.75%), indicating potential areas for optimization in doping concentration and film preparation techniques.
1：Experimental Design and Method Selection:
Strontium-doped Cu2O thin films were prepared using the Nebulizer spray technique with different doping concentrations (0, 3, 5, and 7%).
2：Sample Selection and Data Sources:
The films were characterized using XRD, AFM, Raman, UV–Vis, photoluminescence, and Hall effect measurements.
3：List of Experimental Equipment and Materials:
Equipment used includes Bruker AXS D8 XRD, Princeton Acton SP 2500 Raman spectrometer, AFM Park Scientific Instruments AutoProbe CP, PerkinElmer LS55 fluorescence spectrophotometer, and Hall effect measurement setup.
4：Experimental Procedures and Operational Workflow:
The films were deposited on preheated substrates at 280°C, followed by characterization and solar cell fabrication.
5：Data Analysis Methods:
Data were analyzed using Scherer formula for crystallite size, Tauc’s relation for band gap, and standard formulas for electrical properties.
