研究目的
Investigating the chemical bath deposition of In2S3 thin films as a promising material and buffer layer for solar cells, focusing on their elemental composition and microstructure.
研究成果
The study successfully deposited In2S3 thin films using CBD, characterized their microstructure and composition, and identified the presence of minor contaminants. The findings suggest potential for these films as buffer layers in solar cells, with further optimization needed to reduce impurities.
研究不足
The study is limited by the specific conditions of chemical bath deposition and the materials used. Potential areas for optimization include the reduction of oxygen and carbon contamination in the films.
1：Experimental Design and Method Selection
Chemical bath deposition (CBD) was used to deposit In2S3 thin films on sital and glass substrates. The synthesis involved a wine-hydroxylamine aqua solution containing In(NO3)3, CH3CSNH2, C4H6C6, and NH2OH·HCl at 353 K and pH = 1.7.
2：Sample Selection and Data Sources
Sital and glass substrates were used for deposition. The thickness of the films ranged from 290 to 760 nm.
3：List of Experimental Equipment and Materials
Shimazu XRD - 7000 device for crystal structure study, AURIGA CrossBeam scanning electron microscope (Carl Zeiss NTS, Germany) for surface and composition study, ESCALAB MK II (VG Scientific, Great Britain) spectrometer for XPS analysis.
4：Experimental Procedures and Operational Workflow
Deposition was carried out at specific temperatures and pH levels. The films were annealed in argon in a SNOL 8.2/1000 furnace to study thermal effects.
5：Data Analysis Methods
X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), and X-ray photoelectron spectroscopy (XPS) were used for analysis.
